摘要： A method of selecting antennas (6, 10; 32, 48-50) for communication between the receiver side and the transmitter side of a wireless MIMO system includes obtaining channel state information representative of channel transfer functions between combinations of transmitter and receiver antennas, and performing at least once an iterative algorithm for calculating an optimised parameter vector for a family of parameterised discrete probability density functions giving a higher probability to states representing a selection of antennas giving a more desirable value of a target function based on the channel state information and an optimised value of the target function calculated for at least one sample state drawn at least in part according to the probability density function obtained using the current parameter vector. At least a final performance of the iterative algorithm uses selections of both a number Nr of receiver antennas (10; 32) and a number N , of transmitter antennas (6; 48-50) to calculate values of the target function, so as to arrive at a selection of both a sub-set of all available transmitter antennas (6; 48-50) and a sub-set of all available receiver antennas (10; 32).
