Abstract
The invention relates to the field of channel coding and modulation technique, more specifically, to a single-carrier channel estimation method, comprising: equalizing a carrier of an input current-frame signal and of a channel of the current-frame signal, to obtain a sequence code of the current-frame signal, decision value of transmission sequence of the current-frame signal and estimated value of signal-to-noise ratio of the current-frame signal; calculating the current-frame signal, the sequence code and the estimated value of signal-to-noise ratio to obtain a initial channel estimation; calculating the current-frame signal, the decision value of transmission sequence and the estimated value of signal-to-noise ratio to obtain a reference channel; obtaining a filtered channel value after filtering the reference channel; and obtaining the estimated channel of the next-frame signal after implementing adaptive filtering on the estimated value of initial channel and filtered channel value, by reference to the reference channel.
