| 摘 要： | 分析在不同离散时间信道下和同一离散时间信道不同的抽头下ZF和MSE线性均衡器的均衡效果,将两种准则应用于多输人多输出（MIMO）系统均衡中,与最大似然（ML）检测和基于球形译码算法（SD）的检测做比较。理论和仿真结果表明：线性均衡器能降低符号间串扰,并且抽头数越多均衡效果越好,但当抽头数达到一定值时,均衡效果的进一步改善不大。MIMO系统中基于MSE准则的判决反馈均衡器优于线性均衡器,SD算法可用较少的计算量获得最接近ML检测的性能。

| Abstract: | Analyzes the performance of ZF and MSE equalizer in two cases.One is in different discrete-time channels,the other is in the same discrete-time channel with different taps.The criteria are also adapted to MIMO equalization,and compared with ML detection and SD detection methods.Theoretical analysis and emulation results show that linear equalizer can reduce ISI.The equalization effect is on a rise as the number of equalization taps increases,but it can not get improved when the number of taps is large enoug... |
