ABSTRACT:
A method transmits training frames in a MIMO system. A long sequence of training frames is transmitted from a station B to a station A via a channel of the MIMO system, in which the station A includes NAantennas and NA—SSRF chains and the station B includes NBantennas and NB—SSRF chains, and a number of frames in the long sequence of training frames is at least equal towhereis a lower bound operator. A short sequence of training frames is transmitted from the station A to the station B via the channel in response to receiving the long sequence of training frames. A number of frames in the short training sequence is at least equal to
