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

This paper extends previous works [1][2][3] 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 is relatively easy to obtain, provides many useful information, and gives a good comparison with the simulation results of realistic systems [5][6]. Keywords—Matched filter bound, QAM modulation, equalization and diversity combining.
