Abstract:
1. A method comprising: at each of a first plurality of antennas of a first wireless communication device, receiving a transmission associated with each of one or more spatial streams that are transmitted via a second plurality of antennas of a second wireless communication device, wherein the transmission comprises at least first and second training fields which are configured for channel estimation; and computing multidimensional channel matrix information between the first plurality of antennas and the second plurality of antennas from receive values in the first and second training fields, a spatial mapping vector, and a cyclic diversity vector, wherein computing the multidimensional channel matrix information comprises calculating the multidimensional channel matrix information having a dimension one above a number of the spatial streams transmitted by the second wireless communication device and less than or equal to a number of the first plurality of antennas and a number of the second plurality of antennas.
