And improve the performance by use of the decision feedback equalization 并提出了决策反馈均衡对系统性能的改善。
Then we focus on decision feedback equalization ( dfe ) algorithm which is widely used in mimo signal detection . subsequently , a minimum mean squared error ( mmse ) detector based on wl detection combined with the decision feedback strategy for ca - mimo is derived . meanwhile , the issue that how to use wl detection in da - mimo system is discussed and a solved project is also presented 本文第四章在介绍了宽线性检测技术的基础知识之后,着重针对mimo信号检测算法中使用广泛的反馈判决检测算法,提出了一种基于最小均方误差准则的宽线性反馈判决集中式mimo信号检测算法;同时,结合第三章的内容,对分布mimo信号如何采用宽线性检测提出了一套解决方案,通过计算机仿真,给出了几种分布mimo检测算法的性能;结果表明,在采用最优检测顺序的情况下,两
