Abstract
A method and apparatus for implementing spatial diversity utilizing coaxial interconnections between a plurality of receivers, transmitters and radiating elements in a communication system is disclosed. The long coaxial line used for feeding associated receive antennas is used for creating delay of a signal for implementing downlink diversity. Similarly, the long coaxial lines used for feeding associated transmit antennas are used for creating delay of a signal for implementing uplink diversity. The method and apparatus, in particular, further includes utilization of at least one of the radiating elements for receiving a signal and transmitting a delayed version of a signal to be transmitted.
