Method and system for communication channel optimization in a multiple-input multiple-output (MIMO) communication system |
摘要 |
A transmission method in a multiple-input multiple-output (MIMO) communication system, a transmitter in a MIMO communication system and a MIMO communication system are provided. The method comprises the steps of: receiving feedback data representing channel state information from respective receivers of the MIMO communication system; grouping the receivers into one or more groups based on the received feedback data; obtaining a precoding matrix for each group of receivers based on the received feedback data such that precoding vectors or sub-matrices in the precoding matrix associated with respective receivers of said each group of receivers are orthogonal to each other; and applying the precoding matrix to input signals for transmission to said each group of receivers.
