A MIMO method based on distributed transmission sources for transmitting a downlink data stream between M transmitting antennas and a mobile terminal having P receiving antennas, M and P>1, channels from at least two transmitting antennas to one of receiving antennas have different multipath distributions, comprises transmitting a different sub-data stream of M sub-data streams from the M transmitting antennas respectively to the mobile terminal by using the same spreading code: estimating multipath channel matrix of channels from the M transmitting antennas to the receiving antenna, which use the spreading code: and processing transmitted signals corresponding to the M sub-data streams received by the receiving antenna based on the multipath channel matrix of each receiving antenna, to restore the downlink data stream.
