Abstract
A communication system having a plurality of forward channel communications and a plurality of corresponding reverse channel communications from and to a plurality of mobile users. A plurality of broadcaster transmitters are distributed at macro-diverse locations for transmitting forward channel signals to the users under control of a broadcaster control unit. A plurality of collectors are distributed at macro-diverse locations for receiving reverse channel signals from the users which are processed to yield one or more sequences of data bits as a burst and corresponding initial confidence metrics for each bit. The collectors forward these reverse channel signals including the data bits and corresponding processed confidence metrics to aggregators. The system includes bandwidth control for minimizing backhaul bandwidth from collector to aggregator while maximizing signal quality.
