摘要

作者提出了一种不对称结构，在便携性上降低了复杂性。它在基站使用决策反馈均衡器(DFE)来均衡来自便携式设备的数据，在基站使用Tomlinson-Harashima预编码器及其前向滤波器(TH-FF)来预均衡传输到便携式设备的数据。所有滤波器仅使用基站上的可用信息来表征。给出的性能结果包括误码率、信号功率和频谱密度，数据速率在10到100 Mbits/s之间，以及对自动增益控制误差的灵敏度。使用定制设计的ASIC，基站的复杂性对于高达20mbit /s的速率似乎是可行的。

Asymmetric signal processing for indoor wireless LANs

The authors propose an asymmetric structure with reduced complexity at the portable. It uses a decision feedback equalizer (DFE) at the base station to equalize data from the portable and a Tomlinson-Harashima precoder with its forward filter (TH-FF) at the base station to pre-equalize transmission to the portable. All the filters are characterized using available information at the base station only. Performance results presented include bit error rates, signal powers and spectral densities for data rates between 10 to 100 Mbits/s and sensitivity to automatic gain control errors. Using custom designed ASIC, the complexity at the base station appears feasible for up to a 20 Mbits/s rate.
