Abstract: A communication system having an adaptive antenna array subsystem generates calibration information for the adaptive array subsystem by measuring the amplitude and phase of modulated signals within the subsystem at the antenna array mount and at the back plane mount for the transmit and receive array. The calibration information is used to more accurately perform beamforming for both received an transmitted information signals. The communication system uses a time diversity duplex (TDD) synchronous code division multiple access (SCDMA) protocol for wireless communication between remote terminals and a base station. The calibration means uses a combination combiner and splitter having matched micro strip lines incorporated into a printed circuit board in either the antenna array mount or the back plane.
