A Blind Signal Recovery and Detection Algorithm Using Precoding Technique

提出了一种用于多输入多输出信道的,基于预编码技术的盲信号恢复与检测算法.在发送端,对每个用户输出符号的模进行预编码;在接收端,利用改进的代数常模算法进行信道的补偿和信号检测.该算法能一次性的、显式的获得针对每个用户的均衡器,并分离出用户发送的符号,有效地去除码间干扰和用户间干扰.模拟结果显示,该算法具有简洁、可并行处理和抗远近的特点.

A new blind signal recovery and detection algorithm based on precoding technique for MIMO channel is (proposed).On the transmitter side the modulus of all users' data is precoded,while on the receiver side the improved ACMA algorithm is applied to efficiently remove both the inter-symbol-interference (ISI) and multi-user-interference (MUI).A one-shot and closed-form equalizer is obtained for each user. Simulations show the proposed algorithm is simple,parallel and near-far resistant as well.
