IEEE TRANSACTIONS ON SIGNAL PROCESSING 2012年 第10期60卷 5230-5240页
作者: Baron, Dror Weissman, Tsachy N Carolina State Univ Dept Elect & Comp Engn Raleigh NC 27607 USA Stanford Univ Dept Elect Engn Stanford CA 94305 USA
Motivated by the Markov Chain Monte Carlo (MCMC) approach to the compression of discrete sources developed by Jalali and Weissman, we propose a lossy compression algorithm for analog sources that relies on a finite re... 详细信息
