Vision

      A new class of equalization techniques, Chained Turbo Equalization for Block Transmission (CHATUE) is investigated in this research project for block transmission over the channels suffering from fading frequency selectivity due to multipath propagation. The ultimate goal of this project is to completely eliminate the necessity for appending cyclic prefix (CP) and/or locating guard interval (GI) between the blocks to be transmitted over the multipath channels. Convergence and asymptotic properties of the proposed techniques are analyzed through information theoretic approach to identify the achievable limit of performances. Furthermore, a series of simulations using multi-dimensional channel sounding field measurement data is to be conducted for realistic performance verification of the proposed techniques. This project aims to solve the problems in block transmission techniques without CP/GI from the viewpoint of the network information theory, where EXIT analysis is no longer two dimensional. We need more sophisticated analytical tool in solving this problem.
