General minimum Euclidean distance-based precoder for MIMO wireless systems
收藏 引用
EURASIP JOURNAL ON ADVANCES IN SIGNAL PROCESSING 2013年 第1期2013卷 1页
作者: Quoc-Tuong Ngo Berder, Olivier Scalart, Pascal Univ Rennes 1 IRISA Rennes France
In this article, we investigate the linear precoder based on the maximization of the minimum Euclidean distance between two received data vectors. This new precoding matrix is expressed as the product of a power alloc... 详细信息
