Adaptive Block Linear Equalizer for Block Data Transmission Systems

This paper presents an adaptive algorithm that is considered as a modification to the Block Linear Equalizer which is used with Block Data Transmission Systems. The two main factors that influence the noise performance of the Block Data Transmission System are the distortion introduced by the channel and the block size. The proposed algorithm considerably improves the noise performance and hence the transmission efficiency of the system by adaptively reducing the block size of the transmitted signal-elements when the distortion introduced by the channel is high and increasing the same when the channel distortion is low. This advantage is achieved with only a slight increase in the equipment complexity. Index Term— Wireless, Block transmission, Channel distortion, Equalizer
