摘要： The present invention is a communication system having a plurality of forward channel communications and a plurality of corresponding reverse channel communications in a region for communications with cellular users. Each region includes a plurality of zone managers. Each zone manager includes a broadcaster having a broadcaster transmitter for broadcasting a plurality of forward channel communications using broadband broadcaster signals to form a plurality of broadcaster forward channels. Each zone manager includes an aggregator for processing reverse channel communications. Each zone manager communicates with a collector group for receiving reverse channel communications from users and forwarding reverse channel communications to the aggregator. Each of the users includes a user receiver for receiving a different forward channel from said broadcaster and includes user transmitter means for broadcasting user reverse channel communications in a different user reverse channel. The collector group for each zone manager is formed of macro-diverse collectors some of which are located at other zone managers. By having collectors co-sited at zone manager sites, the macro-diverse collector operations are possible while reducing the installation cost of collectors.

摘要： 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 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 one or more initial confidence metrics for each bit. The initial confidence metrics have an initial range, a.sub.in, represented by an initial number of bits, .gamma..sub.in, and are processed to form processed confidence metrics having a processed range, a.sub.p, represented by a processed number of bits, .gamma..sub.p. The collectors forward these reverse channel signals including the data bits and corresponding processed confidence metrics to aggregators. The aggregators combine the multiple collector signals for the same user received from the macro-diverse collectors. The combining of multiple collector signals for the same user results in an output bit stream for the user with fewer bit errors.

摘要： A cellular communications system that includes forward channel communications to users and corresponding reverse channel communications from mobile users. The users travel from one area to another area over one or more zones. The forward channel communications are broadcast directly to users in a broadcaster zone. The reverse channel communications from users are not returned directly but are first collected at locations arrayed over the broadcaster zone. After collection, the reverse channel communications are forwarded to complete the full duplex communications. The forward channel communications are point to multipoint while the the reverse channel communications are multipoint to point. The communication system separately handles the point to multipoint forward path as a direct broadcast and the multipoint to point reverse path using multiple collection points. Since the forward and reverse paths are separately configured, the present invention optimizes both the forward and reverse paths.

摘要： TDMA communication system having forward channel communications and corresponding reverse channel communications between mobile users and a zone manager in an arbitrarily large broadcaster zone established by a broadcaster. The users are located within the broadcaster zone and the collectors are distributed in proximity to the broadcaster zone. The zone manager operates to control the selection of users to form user groups and for selecting collectors to form collector groups such that the difference between the propagation times from broadcaster to user to collector among users active with the same collector does not exceed a synchronization error such that user reverse channel signals at the collector are isolated from each other. Users are selected such that each of the users in the user group are located at a distance from each of said other users in the user group not greater than a distance UR.sub.max. Collectors are selected such that each of the collectors in a collector group is located at a distance from each of the other collectors in the collector group not greater than a distance C.sub.max where CR.sub.max is a value such that user reverse channel signals at the collectors are isolated.
