| 1. A structure comprising:
a input port for receiving a plurality of baseband signals;
a baseband signal processing network for receiving the plurality of baseband signals and providing two or more sets of in-phase
and quadrature-phase processed and filtered baseband signals to a quadrature modulator for quadrature modulation, wherein
said two or more sets of in-phase and quadrature-phase processed and filtered baseband signals comprise a processed in-phase
and quadrature-phase cross-correlated Time Division Multiple Access (TDMA) baseband signal set and a processed in-phase and
quadrature-phase Code Division Multiple Access (CDMA) or processed Code Division Multiplexed (CDM) baseband signal set; and
a set of two or more transmit amplifiers to amplify and couple the quadrature modulated amplified signals to two or more antennas.
