1. A multiuser (MU) multiple antenna system (MAS) comprising:

  • one or more centralized units communicatively coupled to multiple distributed transceiver stations via a network;

    the network consisting of wireline or wireless links or a combination of both, employed as a backhaul communication channel;

    the centralized unit transforming a first plurality of N data streams into a second plurality of M modulated streams, such that no single M modulated stream carries the complete data of any of the N data streams;

    the plurality of M modulated streams being sent over the network to the distributed transceiver stations;

    the distributed transceiver stations simultaneously sending the plurality of M modulated streams over wireless links to a plurality of client devices such that the combination of the plurality of M modulated streams as received at each client device location results in a modulated stream carrying the complete data of at least one of the plurality of N data streams.
