Abstract

This paper presents an equalization structure in which antenna diversity, adaptive decision feedback equalization (DFE), interleaving and trellis-coded modulation (TCM) can be effectively combined to combat both ISI and cochannel interference in cellular mobile radio environments. The feedback filter of the DFE can use either tentative or final decision symbols of the TCM Viterbi decoding to cancel tail ISI with the square root Kalman algorithm. A performance bound on the average pairwise error probability for TCM under perfect interleaving and equalization is obtained by analysis. Some simulation results which illustrate the potential of the proposed system will also be given. In particular, a performance comparison between the proposed method and uncoded QPSK modulation will be undertaken.
