ABSTRACT:
A diversity technique for use in a multichannel receiver such as a cellular base station which includes at least a pair of wideband digital filter bank analyzers, or so-called channelizers, to provide digital output signals representing the signals received from a number of mobile subscriber units operating in or near the cell in which the base station is located. Samples of the digital output signals are presented to a time division multiplex (TDM) bus in a predetermined sequence, such as in a sequence which increases incrementally by channel number. A diversity decision is then made by processing each of the channelizer outputs for each channel in the sequence, to determine which one of the outputs contains the strongest receive signal. The channelizer path so determined is then connected to the rest of the base station, on a per channel basis, through a delay unit and multiplexer. As a result, the diversity-enhanced outputs remain in the same time division multiplex, pre-defined sequence so that further base station processing, such as demodulation, can occur in the same way as for a wideband base station system which does not take advantage of diversity techniques.
