Disclosed are a channel statistical information obtaining method and a receiver. The method comprises: a receiver receives, during F time slots, received pilot signals comprising pilot signals sent by a transmitter, wherein F is an integer greater than or equal to 1; the receiver calculates, by using the received F received pilot signals, a covariance matrix of received signals of the receiver over a channel for transmitting the pilot signals; the receiver performs signal reconstruction based on compressive covariance sensing by using the covariance matrix, to obtain a reconstruction signal for sparse statistical information of the channel; the receiver obtains final statistical information of the channel by using the reconstruction signal. Embodiments of the present invention can improve the accuracy of channel statistical information.
