"Data communication at rates near or above 2 kbps on 3 khz-bandwidth HF radio channels is subject to impairment from severe linear dispersion, rapid channel time variation and severe fading. In this investigation recorded 2.4 kbps QPSK signals received from HF channels were processed to extract a time-varying estimate of the channel impulse response, and also to simulate a fast-adapting decision feedback-equalizing receiver. From the estimated channel impulse responses performance-related parameters were computed for ideal matched filter, maximum-likelihood sequence-estimation (MLSE) and decision feedback equalization (DFE)"--Abstract. gccst Radio gccst Communications equipment gccst Comparison Canada.
