Performance Evaluation of Complex Spreading MIMO Systems in Rayleigh Fading and Interference

摘要

In this paper, we evaluate the bit error rate (BER)performances of digital communication systems that employcomplex spreading modulation schemes in Rayleigh fading forvarious jamming scenarios. The jamming signals are barragenoise, pulsed noise, and tone jamming. Specifically, we considerquadrature phase-shift keying (QPSK) and 64-ary quadratureamplitude modulation (64QAM). For these modulations, wederive the BER performances for various diversity combinationsof transmit and receive antennas. In particular, we emphasizethe multiple-input, multiple-output (MIMO) configurations.
