DATA MESSAGE BIT SYNCHRONIZATION AND LOCAL TIME CORRECTION METHODS AND ARCHITECTURES

摘要

Methods and architectures for data message bit synchronization of a spread spectrum signal having a repeating sequence of pseudorandom code bits (314) modulated with data message bits having a data bit time that is an integer number of a repeat time of the pseudorandom bits (314). In one embodiment, an adjusted bit sync offset time is determined for each of a plurality of signals for which bit sync offset time is not known based on a corresponding clock error corrected propagation time for each signal, based on a known bit synch offset time and based on a clock error propagation time of the signal for which bit synch offset time is known.
