摘要
为了实现有效的高速通信,色散信道必然引入符号间干扰。克服干扰的有效技术就是均衡。为此,提出了一个双目标代价函数,不同于以前的单目标代价函数。并给出了其实现算法和仿真结果,通过性能比较可以看出建议的准则和算法是有效的。
For high-speed digital data transmission over a communication effectively,the adverse effects of the dispersive channel cause intersymbol interference (ISI),which should be combated by equalization techniques.In this paper,we propose a special equalization cost function,which includes two object functions.It is not different from all of the previous single object functions for equalization, for which the implementation algorithms are summarized for this new criterion.The performance comparison shows that the proposed cost function is better.
