摘　　要：多天线是LTE系统的一项关键技术,作为一种增强通信系统的方法,它能有效地提高系统容量。然而在实现性能改进的同时,也使得算法的复杂度有所增加,这对高速率要求的LTE系统来说是一个挑战。本文首先对双天线处理进行了理论分析,继而结合picochip多核并行处理器芯片的特点,给出一种了LTE下行双天线空时处理的高效实现方案,并对该方案进行了详细地说明,最后在10M带宽条件下进行测试,分析该方案的特点,对在picochip芯片上的通信系统实现具有一定的通用性。MIMO（Multiple-Input Multiple-Output） is one of the key technologies of LTE system. As a way of enhancing the tele- communication system, MIMO can improve the system capability effectively. Though the performance is improved, the complexity is also increased, which is a huge challenge to the high-rate required LTE system. In this paper, the theory of MIMO and the feature of picochip multiple-core DSP are analyzed firstly, then an implementation of LTE downlink space-time-process on picochip is given with a detailed description and 10M bandwith test, whose characterise is analyzed, which is generic to picochip DSP.
