Abstract (en)
[origin: WO02080375A2] The present invention presents a method and apparatus for phase hopping and space-time coding signals for transmission on multiple antennas (160,162,164,166). The method and apparatus provides expansion of a N x N' space time block code to a M x M' space time block code, where M>N, by using phase hopping on the symbols within the N x N' space time block code to allow transmission of the space time block code on a number of diversity antennas greater than N'. A result of M antenna diversity may be achieved for M transmit antennas.
