Simplified Receiver Design for WLAN System with Packet Binary Convolutional Coding Transmission
Wen Ma · Modern Electronics Technique · 2009
For WLAN system with Packet Binary Convolutional Coding(PBCC) transmission,the receiver is composed of two parts:pre-filter and reduced state equalizer.Whitened Matched Filter(WMF) is generally used as the pre-filter to make the whole system meet minimum phase requirement.The reduced state equalizer is adopted to reduce the complexity of MLSE.In order to reduce the computation burden of pre-filter process,a new pre-filter design method is proposed,which uses zero-forcing rule to calculate the pre-filter coefficients.Computer simulation results indicate that when such receiver design is adopted,the complexity of the receiver is decreased greatly,while performance of the receiver is comparative with the traditional design method.
