ABSTRACT:
Methods and apparatus are presented to provide transmit diversity gains to non-transmit diversity configured remote stations by correlating the magnitude of the interference between at least two antenna paths. A first time-varying transformation is applied to a stream of modulation symbols to form a first transmission signal and a second time-varying transformation is applied to the stream of modulation symbols to form a second transmission signal, wherein the second time-varying transformation has a different relative phase from the first time-varying transformation.
