Claim Text:
1. A channel estimation method, comprising: determining a channel space related matrix of each channel according to first signals received by N antennas of a receiver on each channel of M channels, wherein the channel space related matrix of each channel is used to indicate space correlation between the N antennas on each channel, wherein N is a positive integer greater than 1, and M is a positive integer; determining a channel fading factor filter matrix according to the channel space related matrices of the M channels, wherein the channel fading factor filter matrix is an N×N-dimensional matrix; and determining channel estimation of a first channel according to the channel fading factor filter matrix and channel fading factors corresponding to the N antennas when the N antennas receive first signals on the first channel, wherein the first channel is one of the M channels.
