Abstract:
1. A method of receiving a plurality of simultaneously transmitted data streams, wherein each of the data streams is divided into portions and transmitted at predetermined frequencies and times according to a frequency-hopping pattern, the method comprising: receiving the portions using a plurality of receivers, where each of the plurality of receivers is configured to receive portions transmitted on one of the predetermined frequencies; temporarily storing the received portions in a memory such that the received portions are stored as a function of receiver and time; comparing the stored portions to the frequency-hopping pattern; determining if any combination of the stored portions corresponds to the predetermined frequencies and times of the frequency-hopping pattern; wherein each of the predetermined frequencies includes a plurality of discrete channels configured for data transmission thereon, wherein portions of a data stream are transmitted on any of the plurality of channels according to the frequency-hopping pattern, the method further including; processing signals received by each of the plurality of receivers to separate the plurality of channels; temporarily storing the received portions in the memory such that the received portions are stored as a function of channel and time; said frequency-hopping pattern is a single pattern which is common to and applied across all of said plurality of receivers; wherein the frequency-hopping pattern is a current frequency-hopping pattern, and further comprising: changing from the current frequency-hopping pattern to a new frequency-hopping pattern; comparing the stored portions, as the function of receiver and time, to the current frequency-hopping pattern and the new frequency-hopping pattern; and determining if any combination of the stored portions corresponds to the predetermined frequencies and times of one of the current frequency-hopping pattern and the new frequency-hopping pattern.
