Performance of Complex Spreading MIMO Systems With Interference

Abstract

The objective of this thesis is to investigate the performances of digital communication systems that employ complex spreading modulation schemes in a Rayleigh fading channel. First, we examine binary modulation systems with multiple-input, single-output (MISO) configurations. Later, we study MISO systems for complex spreading modulation systems in general. We demonstrate the performances of specific and widely used modulation schemes such as quadrature phase-shift keying (QPSK), 16-quadrature amplitude modulation (16-QAM) and 64-quadrature amplitude modulation (64-QAM). We also investigate the performances of the previous systems for multiple-input, multiple-output (MIMO) configurations for various combinations of transmit and receive antennas. In all systems, we apply maximal ratio combining (MRC) in order to obtain the maximum signal-to-noise ratio for MIMO systems. Finally, for all the different systems and configurations, we evaluate their performances for a Rayleigh fading channel and in the presence of different types of jamming (barrage noise jamming, pulsed-jamming and tone jamming).
