Abstract
The invention relates to the field of terrestrial broadcast transmission, more specifically, to a channel estimation method. A channel estimation method used for estimating a channel of a next carrier signal frame, the channel estimation method comprising: equalizing a carrier of the current signal frame and of the channel of the current signal frame, to obtain a transmission sequence of the current signal frame and a signal-to-noise ratio of the current signal frame, calculating the transmission sequence to get the reference channel, generating an initial channel estimation based on the signal-to-noise ratio of the signal frame, processing the estimated initial channel and the reference channel by an adaptive filtering method, to obtain an estimated channel of next signal frame.
