  • A simple transmit diversity technique assumes that channel does not change over two symbol period of time. Therefore, this technique is not suitable for time varying channels. This paper modifies the transmit diversity technique to accommodate time varying channel (mobile multipath channel). Simulation results show that the proposed modification works well in fast varying channel.
