Delay diversity is implemented within a wireless system in a manner that can achieve a relatively flat spectrum in a receiving device. In at least one embodiment, phase shift values from an orthogonal P×N matrix A are used to provide phase shifts to a data packet to be transmitted from N transmit antennas, in a single spatial stream, to a remote wireless device. The matrix A is an orthogonal matrix with A·AT=P·I and P≧N. Delay diversity values are also provided to the data packet before transmission. |
