Abstract
The present invention presents a method and apparatus for phase hopping and space-time coding signals for transmission on multiple antennas. The method and apparatus provides expansion of a N×N′ space time block code to a M×M′ space time block code, where M>N, by using phase hopping on the symbols within the N×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.
