摘要

针对时空二维处理技术工程实现时运算量大的问题

分析了算法实现时的性能与运算量之间的关系

给出了分阵元并行处理的解决方法.计算机仿真实验表明

在运算量明显降低的情况下

同时天线阵输出的用户信号的信干噪比可以明显提高.

Abstract

For the problem of huge computing burden in the realization of space-time processing

the relationship of computing burden and system performance is analyzed.A new parallel method based on independent elements processing in the antenna array is proposed.Computer simulations show that

with a remarkable decrease of computing burden

the precision of the estimated vector channel impulse response is enough for the extract of the channel parameters

and the SINR of the array output can be increased observably.
