Multicast Linear Precoding for MIMO-OFDM Systems
Communications Letters, IEEE (2015)
摘要
Multiple-inputmultiple-output (MIMO) orthogonalfrequency division multiplexing (OFDM) multicasting system is considered. For a real-time multicast MIMO-OFDM system, we propose a non-iterative and simple linear precoding that consists of a linear sum (LS) of the corresponding channels. Through numerical results, we show that a minimum user rate of the proposed LS precoding is almost identical to its performance upper bound, which can be obtained through max-min rate maximization.
