Abstract
The ionospheric HF communications channel is a typical dispersive channel. Its rapid change, time-domain broadening, frequency-domain dispersion and deep fading caused by multipath propagation seriously affect the transmission quality. In this paper, the m sequence is used for wideband detection of HF link, and the link delay information and Doppler spread information are obtained. At the same time, aiming at the problem of poor adaptability of Doppler spread estimation algorithm under different SNR, an improved Doppler spread estimation method based on dynamic threshold is proposed, which achieved good results under different SNR.
