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检测方案。该检测器由分数抽头判决反馈均衡器(FDFE)和Clark所提出的伪四进系统组合而成。对于140Mb/s 16QAM和64QAM的计算机模拟结果表明该方案可以达到良好的性能/复杂性折衷。
This paper presents a new detection scheme to overcome the intersymbol interference caused by multi-path fading in high-capacity digital microwave. The detector consists of a fractional tap decision feedback equalizer (FDFE) and a pseudo-quaternary system proposed by Clark. Computer simulations of 140Mb / s 16QAM and 64QAM show that this solution achieves good performance / complexity tradeoffs.
