摘要

For pt.I see ibid., vol.37, no.6, p.601-11 (1989). A pure phase-coherent frequency-hop (FH) system is described, and a digital receiver based on maximum-likelihood estimation of the phase of the frequency-hopped carrier is suggested. The theory developed in pt.I is used in the analysis of the receiver whose performance in the presence of both additive white Gaussian noise and partial-band interference is evaluated. By comparison to the bit error rate performance of noncoherent FSK systems, it is found that for channels without excessive phase distortion, an improvement is achievable with the coherent system, but at a price of a more complex transmitter and receiver.
