本文提出一种用于克服大容量数字微波中由于多径衰落所引起的码间干扰的新算法。该算法是由自适应分数抽头判决反馈均衡器(AFDFE)和所谓的(M,m,L)算法所组成。140Mb/s64QAM信号的计算机模拟结果表明,该算法可以达到良好的性能复杂性的折衷。
This paper presents a new algorithm for overcoming the intersymbol interference caused by multi-path fading in high-capacity digital microwave. The algorithm consists of an adaptive fractional tap decision feedback equalizer (AFDFE) and a so-called (M, m, L) algorithm. Computer simulation of the 140Mb / s64QAM signal shows that the algorithm can achieve a good compromise between performance and complexity.
