Riassunto

This thesis examines the effects of multipath interference on Low Probability of Intercept (LPI) waveforms generated using intersymbol dither. This thesis expands on prior work by examining the effects of multipath interference on cooperative and non-cooperative receiver performance to assess the above method's effectiveness using a more realistic model of the physical transmission channel. The performance of a Minimum Mean Squared Error (MMSE) cooperative equalizer and a Constant Modulus Algorithm (CMA) non-cooperative equalizer are examined. Simulation results suggest that it is possible for cooperative receivers to accurately demodulate a transmitted waveform in multipath conditions, while degrading non-cooperative receiver performance. Several randomly generated multipath channels exhibited extremely poor equalization results, indicating a level of algorithm sensitivity to multipath conditions.
