摘要
En 中文
Multiple-input multiple-output (MIMO) orthogonal-frequency 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.
