A high capacity broadband base station employs a wideband radio and phased array processing subsystem. This phased array antenna subsystem contains multiple sets or pairs of alternating receive only and transmit/receive elements distributed in a two dimensional spatial array. Each digital wideband radio performs both receive and transmit channel signal processing. In the receive direction, the digital representation of the entire spectrum for each antenna element is divided into channels for the particular waveform of interest. For a 5 MHz PCS GSM, the digital wideband radio separates twenty-four carriers into twenty-four (200 KHz wide) data streams, each of which is representative of a respective channel, and couples each channel to a digital signal processor. In the transmit direction, the radio combines the digital representations of the twenty-four individual channels supplied by the DSP into a single wideband channel for transmission.

[ What is claimed is:] [1.]1. A high capacity broadband base station for a cellular communication system comprising a digital wideband radio coupled to a phased array array subsystem, said phased array antenna subsystem containing multiple sets of alternating receive only and transmit/receive antenna elements distributed in a two dimensional spatial array, and wherein said digital wideband radio is operative to perform both receive and transmit channel signal processing, such that in the receive direction, the digital representation of the entire spectrum for each antenna element is divided into channels for a particular waveform of interest, and in the transmit direction, said digital wideband radio is operative to combine digital representations of individual channels into a single wideband channel for transmission.
