Differential Codebook MIMO Precoding Technique


In this paper, we present a differential codebook precoding technique for MIMO spatial multiplexing systems. The proposed scheme updates the precoding matrix by multiplying the codebook matrix specified by the receiver to the previous precoding matrix. The codebook matrices are designed to include quasi-diagonal matrices for finer quantization of the… (More)
