3-4 Channel Equalization Characteristics of Lapped Near Perfect Reconstruction Transmultiplexer

Abstract

Since OFDM has computational efficient implementation and the robustness against the multipath fading channel, it is widely used in many wireless applications. However, it has also the disadvantages in poor frequency response and redundant insertion of guard interval. In this report, a lapped near perfect reconstruction transmultiplexer is considered as a multi carrier modulation system, and a channel equalizer is proposed. Simulation results show the robustness against the delay spread of the channel.
