2007 IEEE International Symposium on Information Theory, 2007
The availability of noiseless feedback in an additive white Gaussian noise channel can considerably improve the rate of decay of error-probability with block length. A doubly exponential error decay can be attained even in the presence of an additive interference term non-causally known at the transmitter alone.

Broadcasting Dignity and Broadcasting Language
HAN-GEUL, 2017이 글의 목적은 방송의 품위와 방송언어의 관계를 규명하는 데 있다. 방송의 품위는 공공성(진실 가치)과 건전성(도덕적 가치)으로 구성된다. 방송의 품위 기준에 따라서 방송언어의 실용적 평가 요소로 여섯 가지 - 공정성, 정확성, 언어 예절, 인권 존중, 선정성, 폭력성-가 제시될 수 있다. 공정성은 방송언어가 공정하고 객관적인가? 정확성은 어문 규정에 맞게 사용되었는가? 언어 예절은 언어 규범에 맞게 사용되었는가? 인권 존중은 차별적인 표현이나 비하 표현을 사용하였는가? 선정성은 성적 표현이 사용되었는가? 폭력성은 폭력적인 언어가 사용되었는가? 방송언어의 실용적 평가 요소를 바탕으로 방송언어의 분석 항목을 설정할 수 있다. 이

2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008
We study the security of communication between a single transmitter and multiple receivers in a broadcast channel in the presence of an eavesdropper. We consider several special classes of channels. As the first model, we consider the degraded multi-receiver wiretap channel where the legitimate receivers exhibit a degradedness order while the ...

Broadcast-relay-broadcast channels
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010In this paper, we study the achievable rate regions of broadcast-relay-broadcast channels. The source broadcasts information to the users. A number of parallel relays are used to assist users. Each relay receives information from the source and forwards information to users. The relays also broadcast the forwarded information to all users.

[Pra91, Pra92] develop CBS, a CCS-like calculus [Mil89] where processes communicate by broadcasting values along a single channel. These values are hidden or restricted by translation to noise. This paper types CBS and restricts it to processes with a unique response to each input.

Broadcast Authentication and Broadcast Encryption
2014Broadcast authentication schemes that employ only symmetric PRFs include certificates-based schemes like one-time-signatures (OTS), and timed efficient stream loss tolerant authentication (TESLA), and identity-based schemes based on probabilistic subset allocation.

IEEE Transactions on Information Theory, 1972
We introduce the problem of a single source attempting to communicate information simultaneously to several receivers. The intent is to model the situation of a broadcaster with multiple receivers or a lecturer with many listeners. Thus several different channels with a common input alphabet are specified.

1996
In the calculus of broadcasting systems (CBS), speech is autonomous, but hearing takes place only when the environment speaks. This paper develops a timed CBS (TCBS) where no time may pass if there is speech pending. A process wishing to speak can be forced, by attaching a time-out to it, to first listen for a specified length of time.

On Reversibility and Broadcast
2018Causally consistent reversibility relates reversibility in a concurrent system with causality. Broadcast is a powerful primitive of communication used to model several distributed systems from local area networks, including wireless systems and lately multi-agent systems. In this paper, we study the interplay between reversibility and broadcast, in the

Data Broadcasting Solutions for Broadcasters
142nd Technical Conference and Exhibition, 2000With the advent of digital television in the U.S. and worldwide, broadcasters are searching for new opportunities to enhance programming. In addition, many in the industry believe that potential new sources of revenue can be unlocked by providing consumers rich digital content.
