| Abstract | Space-time block-coded transmission over fading intersymbol interference (ISI) channels is investigated. A lower bound on the pairwise error probability for optimum detection is given. Also, an approximation for the bit error rate is derived and compared with simulation results for maximum-likelihood sequence estimation (MLSE) for the GSM/EDGE (enhanced data rates for GSM evolution) system. Furthermore, a novel design rule for space-time block codes (STBC) with arbitrary rate for fading ISI channels is provided. A corresponding full-rate code is designed and shown to yield higher performance than Alamouti's code. It is demonstrated that for fading channels with L independent impulse response coefficients, full-rate STBCs designed for the flat fading channel can achieve at most a diversity order of (NT+L-1)NR if NT transmit antennas and NR receive antennas are used. On the other hand, the maximum diversity order employing the proposed code design rule is LNTNR. |
