Patent ID: 8379769

Claim:
A receiver system configured to receive a hierarchically modulated signal from a transmitter system, said receiver system comprising: a receiver device configured to receive the hierarchically modulated signal that comprises a high priority data stream and a low priority data stream; a high priority processor device in communication with said receiver device, wherein said high priority processor device is configured to process said high priority data stream of said received hierarchically modulated signal, such that an output is emitted that is representative of said high priority data stream; and a low priority processor device in communication with said receiver device, wherein said low priority processor device is configured to process said low priority data stream of said received hierarchically modulated signal, and said low priority processor device comprising: a variable despreader device in communication with said receiver device, wherein said variable despreader device is configured to reconstruct transmitted bits of said hierarchically modulated data stream by integrating received symbols over a variable integration time period corresponding to each said transmitted bit, said variable integration time period being known by the transmitter system and said low priority processor device, and each said symbol having a corresponding said variable integration time period, such that an output is emitted that is representative of said low priority data stream.
