1. A communications method comprising the steps of:
- activating a plurality of signal sources;
transmitting a synchronization event to said plurality of signal sources to cause said plurality of signal sources to simultaneously transmit data using the same modulation technique in response to said synchronization event, wherein said plurality of signal sources store identification data and transmit at least a portion of said stored identification data over a set of available transmission channels in accordance with a multiple pass transmission algorithm having at least one transmission pass, wherein said signal sources utilize portions of said stored identification data to determine said transmission channels in each pass of the multiple pass transmission algorithm; and
demodulating the transmitted data from said plurality of signal sources.
