摘要：A method of estimating channel conditions for use in a MIMO communicationsystem includes the steps of, at a receiver: computing a SINR metric for all pre-coding

matrices; computing a first capacity metric for the bandwidth from the SINR metrics, andselecting a rank which maximizes the first capacity metric; computing a second capacitymetric for each frequency channel from the SINR metrics and the selected rank, andselecting one or more pre-coding matrices which maximize the second capacity metric;computing a third capacity metric from the second capacity metric, selected rank andselected pre-coding matrices for each transmission layer within each frequency channel,and selecting one or more frequency channels which maximize the third capacity metric;and transmitting the selected rank, selected pre-coding matrices and selected frequencychannels to the transmitter for use in subsequent data transmissions.
