Aspects of a method and system for choice of a steering matrix (Q) for sounding in antenna selection are presented. Aspects of the system may include a transmitting station that enables determination of values for a plurality of matrix elements, which are represented in a steering matrix (Q). The contents of the steering matrix may be determined based on the contents of a plurality of protocol data units (PDU). Each of the PDUs may comprise a sounding frame. One or more space-time signals may be generated based on the plurality of PDUs. One or more transmit chain signals may be generated by multiplying a vector representation, which comprises the one or more space-time signals, by the steering matrix. One or more transmit chain signals may be transmitted via transmitting antennas selected from a plurality of transmitting antennas.
