Abstract:
A method for transmitting a signal from a plurality of antennas, said method comprising the steps of:receiving a symbol stream at a transmitter; performing a transform on said input symbol stream to generate a transform result, said transform result comprising an NXNâ€² orthogonal space-time block code, and generating N first signals; non-zero complex weighting, over time, at least one of the N first signals of said transform result to generate at least one second signal, each of said at least one second signals being phase shifted relative to the one of the N first signals from which it was generated, the N first signals and the at least one second signal together forming M signals, wherein M is greater than N; and, transmitting, substantially simultaneously, each of said N first signals of said transform result on one of a first at least one antenna and, each of said at least one second signals on one of a second at least one antenna, thereby to transmit the symbol stream upon M transmit diversity paths.
