Abstract:
1. A receiver synchronization method that significantly reduces the convergence time for synchronization of a receiver to a modulated baseband radio frequency signal comprising the following steps: detecting the start of a modulated baseband radio frequency signal having a known data payload burst size; then determining the characteristics of said modulated baseband radio frequency signal; then not collecting or processing samples of preamble and header symbols and instead detecting the presence of a payload data symbol indicating the presence of payload data that is modulated on said modulated baseband radio frequency signal; only then starting a data acquisition subsystem to begin collecting samples of said modulated baseband radio frequency signal; next transferring said collected samples of said modulated baseband radio frequency signal to a digital signal processor for processing; and, finally said digital signal processor searching for a preamble on said transferred collected samples of said modulated baseband radio frequency signal and determining a timing delay to the start of said payload data symbol indicating the presence of payload data then stopping the collecting of samples by said data acquisition subsystem at the end of the known data payload burst size.
