EURASIP JOURNAL ON ADVANCES IN SIGNAL PROCESSING 2017年 第1期2017卷 1页
作者: Yahampath, Pradeepa Univ Manitoba Dept Elect & Comp Engn Winnipeg MB R3T 5V6 Canada
Consider communicating a correlated Gaussian source over a Rayleigh fading channel with no knowledge of the channel signal-to-noise ratio (CSNR) at the transmitter. In this case, a digital system cannot be optimal for... 详细信息
