| 摘 要： | 目前国内外广泛使用的数字微波140Mb/s、16OAM系统,由于选择性衰落造成的码间干扰,一般都采用基带自适应均衡器予以补偿。本文研究了基带横向均衡器和判决反馈均衡器在不同抽头个数时最小相位衰落和非最小相位衰落的均衡能力、并分析了定时相位偏差对均衡器的影响。

| Abstract: | In the digital microwave 140 Mbit/s 16 QAM Communication systems, the baseband adaptive equalizers are usually used to compensate the intersymbol interference caused by multipath fading. This paper discusses the equalizer ability of transverse equalizer and decision feedback equalizer with different number of taps at both minimum and non-minimum phase fading. The influence of the timing phase deviation on equalizer is analysed. |
