Abstract:
1. A method for transmitting Multiple Input Multiple Output (MIMO) beam forming data comprising: performing MIMO coding on data streams to obtain coded data streams; obtaining weight values W=(W weighting the coded data streams with the weight values W=(W and x j is j th coded data stream; wherein obtaining the weight values comprises (a) or (b), wherein (a) comprises: on a specific set of carriers on the currently selected symbol from the transmitting end to the antenna array of the receiving end, and updating the statistical channel correlation matrix R stat =ρR stat +(1−ρ)R, where H(k) is a channel coefficient matrix of the k th sub-carrier in a specific set of carriers from the transmitting antennas of the antenna array of the transmitting end to the antennas of the receiving end, N represents the number of carriers contained in the specific set of carriers, α k is a constant representing a weight of a correlation matrix of the k th sub-carrier, ρ is a constant, and 0≦ρ≦1, and a superscript H represents conjugate transposition of the matrix, Rx is the number of the receiving antennas of the receiving end; and wherein (b) comprises:
