Error Exponents for the Gaussian Channel with Active Noisy Feedback
Young-Han Kim, Amos Lapidoth, Tsachy Weissman
We study the best exponential decay in the blocklength of the probability of error that can be achieved in the transmission of a single bit over the Gaussian channel with an active…
Exploiting Opportunistic Multiuser Detection in Decentralized Multiuser MIMO Systems
Rui Zhang, John M. Cioffi
This paper studies the design of a decentralized multiuser multi-antenna (MIMO) system for spectrum sharing over a fixed narrow band, where the coexisting users independently updat…
Fast and Near-Optimal Matrix Completion via Randomized Basis Pursuit
Zhisu Zhu, Anthony Man-Cho So, Yinyu Ye
Motivated by the philosophy and phenomenal success of compressed sensing, the problem of reconstructing a matrix from a sampling of its entries has attracted much attention recentl…
Cascade multiterminal source coding
Paul Cuff, Han-I Su, Abbas El Gamal
We investigate distributed source coding of two correlated sources X and Y where messages are passed to a decoder in a cascade fashion. The encoder of X sends a message at rate R_1…
Coherence Analysis of Iterative Thresholding Algorithms
Arian Maleki
There is a recent surge of interest in developing algorithms for finding sparse solutions of underdetermined systems of linear equations . In many applications, extremely l…
An Implementable Scheme for Universal Lossy Compression of Discrete Markov Sources
Shirin Jalali, Andrea Montanari, Tsachy Weissman
We present a new lossy compressor for discrete sources. For coding a source sequence , the encoder starts by assigning a certain cost to each reconstruction sequence. It then…
