Performance of Complex Spreading MIMO Systems With Interference
MetadataShow full item record
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).
