Abstract
The modeling of a digital communication system using complex spreading multiple-input-multiple-output (MIMO) signal with orthogonal covering is discussed in this thesis. Specifically, we examine the MIMO signal that employs fixed and variable length orthogonal covering for both multiuser and multi-rate channels. The approach uses a discrete time formulation to model the signal for Rayleigh fading and various types of jamming interference. The use of variable length Walsh sequences, including concatenation of Walsh-data vectors for simultaneous multi-rate transmissions are explained. The derivations of the noise and interference covariances results are also discussed. In addition, the bit error performances for various jamming scenarios, including barrage, pulsed-noise and tone jamming, are analyzed.
