基于DSP自适应均衡器的实现

Realization of Automatic Adaptive Equalizer Based on DSP

自适应均衡器是实际通信系统中最基本的要素之一,具有改善信道的作用。本文基于TMS320C5000系列DSP,利用其自带的DSPLIB库函数中的卷积函数来实现基于LMS算法的自适应均衡器,给出了算法的程序框图。实验结果表明本算法可以有效的消除码间干扰,具有较高的实用价值。

The automatic adaptive equalizer is one of the basic component parts in practical communication system. It has the function of changing channels. This paper realizes the LMS adaptive equalizer using the convolute function in the DSPLIB functions based on TMS320C5000 serials DSP and gives the flow chart of algorithm. The experimental results show that the ISI can be eliminated effectively with adaptive equalizer in base-band transmission and the method presents in this paper are full of values in practice.
