摘要
The invention relates to a method (100) for estimating channel coefficients of a multi-input multi-output communications channel, the method comprising: receiving (101) a set of receive sequences at outputs of the multi-input multi-output communications channel responsive to a set of transmit sequences provided at inputs of the multi-input multi-output communications channel; and estimating (103) the channel coefficients based on the set of receive sequences and based on a predetermined characteristic of the set of transmit sequences, wherein the predetermined characteristic is such that frequency spectra of the transmit sequences are orthogonal with respect to each other by using zero frequency components alternating with respect to the frequency spectra of the transmit sequences.
