| Abstract: | In this paper, we study DFT-bank transceiverswith filter length longer than the block size. We show how tooptimize the DFT-bank transceiver so that both the intra-band and cross-band interferences are minimized for unknown multipathchannels. No costly post processing technique is needed and theonly channel dependent part is a set of one-tap equalizers at the receiver. The optimization problem is formulated as aRayleigh-Ritz ratio whose solution is well-known. Experiments are carried out for transmission over random multipath channels and the results show that satisfactory SIR performance can beobtained. | ||
