Abstract:
1. A method for detecting a timing synchronization signal for a signal processing system comprising: providing an initial sequence comprised of a plurality of complex numbers, the initial sequence having a preferred autocorrelation property; generating an autocorrelation function of the initial sequence; generating a phase-adjusted autocorrelation vector of the initial sequence by application of a minimization technique; determining a timing uncertainty characteristic of the system; correlating the phase adjusted autocorrelation vector of the initial sequence with a received timing signal within a timing uncertainty window defined by the timing uncertainty characteristic to determine a phase-adjusted autocorrelation function; and detecting a timing synchronization signal by a highest peak of the correlated center portion of the phase-adjusted autocorrelation function; and synchronizing the timing synchronization signal with a received signal to extract data information from a transmitted signal.
