Lost Frequency? The Future of Traditional Radio

My project focuses on the future of traditional radio and answering the question of whether or not it will be able to survive in a digital age. I provided a literature review to offer background of the history of radio and the challenges it has faced during its existence. I addressed five specific areas: television, satellite radio, Internet radio, podcasts, and mobile devices. My creative element consisted of a radio documentary that compiled interviews from professionals in the broadcast industry. I answered three questions in my research: 1.) Do experts in the industry believe traditional radio will be able to survive the emergence of new technologies and non-traditional programming? Or, will these new technologies and non-traditional programming ultimately overcome traditional radio and become the new standard? 2.) In what ways do industry experts believe that the traditional radio format will have to change in order to compete and prevail over new technologies to remain successful? 3.) Which non-traditional radio formats do industry experts believe pose the biggest threat to traditional radio? In conclusion, I found uncertain times--but also times of opportunity and innovation lie ahead for the broadcast industry. Traditional radio will exist for the foreseeable future. As long as the radio dial exists in cars, traditional radio will remain relevant. In order to adapt as digital technology gains popularity, traditional radio must provide programming that is interesting and compelling to satisfy the increased thirst for audio. Keywords: future of traditional radio, disruption, digital audio

The 2010s have seen video games rise to prominence as platforms for game developers, entertainers and advertisers to broadcast their ideas. This paper looks at the major steps in gaming history that led to games as a global mass communication tool, the way the Internet has created an industry built around broadcasting games and the potential future ramifications competitive gaming, emerging technology and intellectual property law hold on the world of video games.

A 21st Century Broadcast Student's Guide to Web Basics: Preparing to be a Multimedia Journalist

This project aims to aggregate recent information on broadcast journalism curriculum and propose a website design to help educate broadcast students about the most-needed web skills in newsrooms. Television reporters

This project aims to aggregate recent information on broadcast journalism curriculum and propose a website design to help educate broadcast students about the most-needed web skills in newsrooms. Television reporters must go beyond re-hashing their broadcast package and script on the station's website, and this includes knowledge of the best site design practices to house more in-depth content. The Grady Undergraduate Survey, as well as the opinions and experience of professionals today, show that web design and web writing skills are two of the most important skills a broadcast student can possess as they prepare to graduate and seek jobs.

On code design for interference channels

There has been a lot of work on the characterization of capacity and achievable rate regions, and rate region outer-bounds for various multi-user channels of interest. Parallel to the developed information theoretic results, practical codes have also been designed for some multi-user channels such as multiple access channels, broadcast channels and relay channels; however, interference channels have not received much attention and only a limited amount of work has been conducted on them. With this motivation, in this dissertation, design of practical and implementable channel codes is studied focusing on multi-user channels with special emphasis on interference channels; in particular, irregular low-density-parity-check codes are exploited for a variety of cases and trellis based codes for short block length designs are performed.

Novel code design approaches are first studied for the two-user Gaussian multiple access channel. Exploiting Gaussian mixture approximation, new methods are proposed wherein the optimized codes are shown to improve upon the available designs and off-the-shelf point-to-point codes applied to the multiple access channel scenario. The code design is then examined for the two-user Gaussian interference channel implementing the Han-Kobayashi encoding and decoding strategy. Compared with the point-to-point codes, the newly designed codes consistently offer better performance. Parallel to this work, code design is explored for the discrete memoryless interference channels wherein the channel inputs and outputs are taken from a finite alphabet and it is demonstrated that the designed codes are superior to the single user codes used with time sharing. Finally, the code design principles are also investigated for the two-user Gaussian interference channel employing trellis-based codes with short block lengths for the case of strong and mixed interference levels.

Practical coding schemes for multi-user communications

There are many wireless communication and networking applications that require high transmission rates and reliability with only limited resources in terms of bandwidth, power, hardware complexity etc.. Real-time video streaming, gaming and social networking are a few such examples. Over the years many problems have been addressed towards the goal of enabling such applications; however, significant challenges still remain, particularly, in the context of multi-user communications. With the motivation of addressing some of these challenges, the main focus of this dissertation is the design and analysis of capacity approaching coding schemes for several (wireless) multi-user communication scenarios. Specifically, three main themes are studied: superposition coding over broadcast channels, practical coding for binary-input binary-output broadcast channels, and signalling schemes for two-way relay channels. As the first contribution, we propose an analytical tool that allows for reliable comparison of different practical codes and decoding strategies over degraded broadcast channels, even for very low error rates for which simulations are impractical. The second contribution deals with binary-input binary-output degraded broadcast channels, for which an optimal encoding scheme that achieves the capacity boundary is found, and a practical coding scheme is given by concatenation of an outer low density parity check code and an inner (non-linear) mapper that induces desired distribution of "one" in a codeword. The third contribution considers two-way relay channels where the information exchange between two nodes takes place in two transmission phases using a coding scheme called physical-layer network coding. At the relay, a near optimal decoding strategy is derived using a list decoding algorithm, and an approximation is obtained by a joint decoding approach. For the latter scheme, an analytical approximation of the word error rate based on a union bounding technique is computed under the assumption that linear codes are employed at the two nodes exchanging data. Further, when the wireless channel is frequency selective, two decoding strategies at the relay are developed, namely, a near optimal decoding scheme implemented using list decoding, and a reduced complexity detection/decoding scheme utilizing a linear minimum mean squared error based detector followed by a network coded sequence decoder.
