dc.description.abstractIn this work , the performance of slow frequency hopped differential phase shift key­ing (SFH/DPSK) systems is analyzed at the block and codeword levels. The effect of error correlation in DPSK demodulation is considered when evaluating block and decoded error probabilities. The exact block and decoded error probabilities are derived and computed for additive white Gaussian noise (AWGN) and partial band noise (PBN). In the presence of tone interference and AWGN, the ranges for the block and decoded error probabilities are computed. These calculated ranges can provide a good estimate of the system performance. The effect of interleaving technique on improving the system performance is addressed under various condi­tions. The performance under worst case jamming is analyzed and the results are presented. A parallel approach to the design of a universal receiver is introduced and applied to SFH/DPSK while the channel has interference from tone jamming and AWGN. It is shown that the designed receiver can always provide a decision error probability which is within a specified degradation from optimality regardless of the time-varying characteristics of the channel.en
