On the Risk of Using Rényi’s Entropy for Blind Source Separation (2009)
Dinh-tuan Pham, Frédéric Vrins, Graduate Student Member, Michel Verleysen, Senior Member
Abstract—Recently, some researchers have suggested Rényi’s entropy in its general form as a blind source separation (BSS) objective function. This was motivated by two arguments: 1) Shannon’s...
Joint Source-Channel Turbo Techniques for Discrete-Valued Sources: from Theory to Practice (2009)
Xavier Jaspar, Graduate Student Member, Christine Guillemot, Senior Member, Luc V
Abstract — The principles which have been prevailing so far for designing communication systems rely on Shannon’s source and channel coding separation theorem [1]. This theorem states that source...
Maximizing Cooperative Diversity Energy Gain for Wireless Networks (2008)
Graduate Student Member, Lin Cai, Jon W. Mark, Life Fellow, Xuemin (sherman Shen, Senior Member
Abstract — We are concerned with optimally grouping active mobile users in a two-user-based cooperative diversity system to maximize the cooperative diversity energy gain in a radio cell. The...
Codes for Asymmetric Limited-Magnitude Errors with Application to Multi-Level Flash Memories (2008)
Yuval Cassuto, Graduate Student Member, Moshe Schwartz, Vasken Bohossian, Jehoshua Bruck
Abstract—Several physical effects that limit the reliability and performance of Multilevel Flash Memories induce errors that have low magnitudes and are dominantly asymmetric. This paper studies...
On the Error Exponents of Improved Tangential Sphere Bounds (2008)
Moshe Twitto, Graduate Student Member, Igal Sason
The performance of maximum-likelihood (ML) decoded binary linear block codes over the AWGN channel is addressed via the tangential sphere bound (TSB) and two of its recent improved versions. The...
