More Information
Summary:Orthogonal multiple carrier data transmission systems are efficiently realized using modified DFT transmultiplexer filter banks. In data transmission applications, a non-ideal transmission channel causes distortions such as intersymbol interference and crosstalk between the subrate bands of the transmultiplexer. Hence, in order to equalize these distortions, subband equalizers, which affect the intersymbol interference and crosstalk behavior, are considered for implementation. The special structure of modified DFT transmultiplexers requires a discussion concerning the various possibilities of placing the subband equalizers at the receiver. Wiener solutions and LMS adaptive algorithms for various new subband equalizer structures are derived and compared by means of simulation results.
