摘要
由于无线信道的多径衰落引起的符号间干扰(ISI)极大地影响了接收端的信号质量,为了对抗ISI引起的信号畸变,通常要在接收端进行信道均衡。该文分析了基于MMSE-DFE的Turbo均衡原理并提出两种低复杂度的改进算法。仿真结果表明,这两种算法性能良好。
Inter-symbol-inference(ISI) caused by multipath fading in wireless channels greatly degenerate the quality of the signal at the receiver,an equalizer usually placed in the receiver in order to combat the distortion of signal caused by ISl.ln this paper,the principle of Turbo equalization based on MMSE-DFE has analyzed and two improved algorithms with low complexity have proposed.The results of simulation suggest that these two algorithms performances are well.
