Abstract

Future wireless personal communications systems are expected to support a wide range of high-quality services that require high data rates. Communicating at high transmission rates over wireless environments, however, creates many difficult problems such as intersymbol interference (ISI) and cochannel interference. In this paper, we present a method which employs an adaptive decision feedback equalization (DFE), interleaving, space diversity and trellis-coded modulation (TCM) to combat both ISI and cochannel interference in cellular mobile radio environments. The feedback filter of DFE uses final decision symbols of Viterbi decoding of TCM to cancel tail ISI with square root Kalman algorithm. Some simulation results which illustrate the potential of the proposed system will be given. In particular, a performance comparison between the proposed method and QPSK system will also be undertaken.
