Abstract
A multipath communication system forms a complex weighted compound signal for transmission through a channel environment wherein the compound signal includes a complex variable weighted compound signal related to a count of available antennas, a power constraint related to each said antenna, and a channel state characteristic.
Claims2
A method of transmitting a multipath communication signal comprising:
- receiving a first independent input signal at a first input node of said multipath communication system;
- receiving a second independent input signal at a second node of said multipath communication system;
- receiving a channel characterization signal at a processor, said channel characterization signal being related to a channel environment of said multipath communication system;
- receiving a transmitter count signal at said processor, said transmitter count signal being adapted to contribute to the identification of a number of available transmitters of a plurality of transmitters;
- receiving a power constraint signal at said processor, said power constraint signal including an individual power constraint value for one transmitter of said plurality of transmitters, said signal transmitters being adapted to couple respective signals into said channel environment;
- with reference to said channel characterization signal, said transmitter count signal and said power constraint signal, preparing a transmittable compound signal including complex variable weighted representations of said first independent input signal and said second independent input signal;
- and
- transmitting said compound signal from said one transmitter into said channel environment.

A method of using an ad hoc communication array comprising:
- identifying a set of communication units and forming a communication unit count value;
- acquiring a power constraint value associated with each said communication unit;
- acquiring channel state information related to a channel environment;
- with reference to said channel state information, said communication unit count value and said power constraint values, preparing a transmittable compound signal including complex variable weighted representations of one or more independent input signals;
- and
- transmitting said complex variable weighted representation as a signal through said channel environment.
