Matched filter bounds on q-ary QAM symbol error probability for diversity receptions and multipath fading ISI channels

This paper extends previous works in matched filter bounds and provides a theoretical calculation of detection probability of q-ary QAM signals transmitted over the diversity reception and multipath fading ISI channels. The matched filter bounds represent the best attainable detection performance of a particular system, which may or may not be realized with a practical system. While an exact analytical expression of detection performance of a transceiver system is difficult to obtain for multipath fading ISI channels, the matched filter bounds are relatively easy to obtain, provide much useful information, and give a good comparison with the simulation results of realistic systems.
