ABSTRACT

In communications systems under jamming interference, it is customary to employ spread spectrum techniques to combat performance degradation. In systems with fading, spatial diversity techniques such as MIMO schemes are usually used to mitigate the problem. Here, we analyze and show the extremely severe effects on BER performance of the combined jamming signals and Rayleigh fading of a system undergoing both conditions at the same time. Then, we analyze and derive the performance of systems employing joint MIMO and complex spreading schemes to combat both Rayleigh fading and jamming and note the significant mitigation improvements.
