A communication system is provided comprising a transmitter coupled to a switch, which is further coupled to at least two antennas for switching the transmit signal to one of the antennas, with no feedback. The communication system further comprises at least one receiver for receiving the transmitted signal.The communication system in the present invention is able to help mitigate the effects of multipath. Previous attempts to mitigate the effects of multipath suffer from various problems: increased complexity needed to measure channel parameters and a feedback loop to switch the transmit antenna based on the parameters.The system is particularly useful when deployed in a MAS system or a jamming system.
