AFCCE, IEEE-BTS and National Translator Association Announce Spring 2020 Scholarship Recipients
The Association of Federal Communications Consulting Engineers (AFCCE), the IEEE Broadcast Technology Society (BTS), and the National Translator Association (NTA) today announced the award of nine scholarships to students interested in telecommunications. Scholarship amounts ranged from $1000 to $5,000. The Spring 2020 scholarship recipients were:
Maurice Compton University of Dallas
Nathan Ellsworth University of Texas at Dallas
Andrew Heller University of Minnesota
Md. Tajul Islam University of Missouri at Kansas City
Daniel Klawson University of Maryland at College Park
Obagaeli Ngene-Igwe University of Cincinnati
Prosanta Paul Old Dominion University
Dylan Stewart Old Dominion University
Rafida Zaman University of Missouri at Kansas City
Mr. Heller is the first recipient of the Byron W. St. Clair Memorial Scholarship, a new program that awards scholarships to promising students, who are planning to pursue a career in broadcast engineering. The St. Clair Scholarship is sponsored by the National Translator Association.
Ellsworth, Islam, Klawson and Stewart received IEEE Broadcast Technology Society/AFCCE Jules Cohen Memorial Scholarships, a program that awards scholarships of up to $10,000 to promising undergraduate or graduate students, who are planning to pursue a career in broadcast engineering. Zaman was the recipient of the E. Noel Luddy Scholarship, sponsored by Dielectric Communications (Raymond, Maine).
“The IEEE Broadcast Technology Society (BTS) is dedicated toward advancing electrical and electronic engineering and by sponsoring the Jules Cohen Memorial Scholarships helps support the next generation of technologists who will become scientists, engineers or technicians developing the next generation of technology driven products and services” said Ralph Hogan, president, IEEE BTS.
“AFCCE is committed to helping develop engineering talent in radio frequency technologies, including antennas, propagation, transmission, and spectrum management. These scholarships represent our largest ever award to promising students whom we hope will help shape the future of telecommunications,” said John George, president of AFCCE.
“NTA congratulates Mr. Heller. This scholarship is a good first step in the tradition of Byron St.Clair to enlighten young minds and encourage more interest in broadcast engineering, especially in the areas of translator and low power television. NTA is happy to join these distinguished organizations in offering this new opportunity that includes students who are entering two-year engineering programs,” said John Terrill, president of NTA.
AFCCE has awarded scholarships for over 30 years to both undergraduate and graduate students, based on qualifications, and financial need. The specific requirements for each scholarship vary, but all applicants must be enrolled in an engineering or related technical curriculum and demonstrate an interest in telecommunications.
Evaluated by an AFCCE scholarship committee including IEEE BTS members, Jules Cohen Memorial Scholarship applicants are ranked based on their explicit interest in broadcast engineering as expressed in a personal statement, their academic record, financial need, and relevant extracurricular activities. Applicants for other AFCCE scholarships have slightly different requirements. Applications for Fall 2020 semester will be accepted beginning March 1, 2020 until April. 30, 2020.

About Association of Federal Communications Consulting Engineers (AFCCE)
AFCCE was founded in 1948 as a professional association of communications engineers practicing before the FCC. The purpose of the Association is to aid and promote the proper federal administration and regulation of those engineering and technical phases of communications, which are regulated by the FCC. In its primary function, the AFCCE monitors the technical policy of the FCC to ensure that the agency's regulations coincide as closely as possible with sound engineering principles. Connect with AFCCE on Twitter @AFCCE, Facebook, and Linked-In.
About National Translator Association (NTA)
NTA fights to ensure that over-the-air television and radio is available for free to residents of smaller communities, however remotely located. More information on NTA is available at http://nationaltranslatorassociation.org
Webinar: ATSC 3.0 Physical Layer and Data Link Layer Overview
13th January 2020
ATSC 3.0 brings IP delivery to over-the-air TV marking a major change in delivery to the home. For the first time video, audio and other data is all delivered as network streams allowing services available to TV viewers at home to modernise and merge with online streaming services better matching the viewing habits of today. ATSC 3.0 deployments are starting in the USA and it has already been rolled out in South Korea for the XXIII Olympic Winter Games in 2018.
Whilst the move to IP is transformational, ATSC 3.0 delivers a whole slew of improvements to the ATSC standard for RF, bandwidth, Codecs and more. In this, the first of three webinars from the IEEE BTS focussing in on ATSC 3.0, we look at the physical layer with Luke Fay, Chair of the ATSC 3.0 group and also a Senior Manager of Technical Standards at Sony.

What is the Physical Layer?
The physical layer refers to the method data gets from one place to another. In this case, we’re talking about transmission by air, RF. Whilst this isn’t, in some ways, as physical as a copper cable, we have to remember that, at a basic level, communication is about making a high voltage in place A change the voltage in place B. The message physically moves from A to B and the medium it uses and the way it manipulates that medium are what we refer to as the physical layer.
In this webinar, Luke will talk about System Discovery and Signalling, defined by document A/321 and the Physical Layer Protocol defined by A/322. Both freely available from the ATSC website. The webinar will finish with a Q&A. Let’s take a deeper look at some of the topics which will be covered.
Choice of modulation
ATSC 3.0 has chosen the COFDM modulation scheme over the previous 8VSB, currently used for first-generation ATSC broadcasts, to deliver data over the air from the transmitter. COFDM, stands for Coded Orthogonal Frequency Devision Multiplexing and has become the go-to modulation method for digital transmissions including for DAB, DAB+ and the DVB terrestrial, satellite and cable standards.
One of the reasons for its wide adoption is that COFDM has guard bands; times when the transmitter is guaranteed not to send any data. This allows the receiver some time to receive any data which comes in late due to multi-path reflections or any other reason. This means that for COFDM, you get better performance if you run a network of nearby transmitters on the same frequency – known as a Single Frequency Network (SFN). A transmitters signal from further away will arrive later, and if in the guard interval, will be used to re-inforce the directly received signal. This means that, counter-intuitively from analogue days, running an SFN actually helps improve reception.
Multiple operating points to match the business case
Another important feature of ATSC 3.0 at the physical layer is the ability to be able to choose the robustness of the signal and have multiple transmissions simultaneously using different levels of robustness. These multiple transmissions are called pipes. As many of us will be familiar with, when transmitting a high bandwidth, the signal can be fragile and easily corrupted by interference. Putting resilience into the signal uses up bandwidth either due using some of the capacity to put error checking and error recovery data in or just by slowing down the rate the signal is sent which, of course, means not as many bits can be sent in the same time window.
Because bandwidth and resilience are a balancing act with each one fighting against the other, it’s important for stations to be able to choose what’s right for them and their business case. Having a high robustness signalm for penetration indoors can be very useful for targeting reception on mobile devices and ATSC 3.0 can actually achieve reception when the signal is below the noise, i.e. a negative signal to noise ratio. A higher bandwidth service delivering UHD at around 20Mbps can be achieved, however, by using 64 instead of 16 QAM.
