PRECODING METHOD AND DEVICE

摘要

A precoding method and device. The method comprises: obtaining the BER upper limit of each precoding matrix in the codebook sets for sign vector sets (s101); according to the obtained BER upper limit of each precoding matrix in the codebook sets, selecting the precoding matrix which makes the BER upper limit minimum to pre-code the input data stream (s102). Based on minimum BER rule, a procoding method and device which can realize minimum BER are provided and the performance of the procoding MIMO system is improved.
