Abstract:
The present invention provides a method and system for generating reference signals that, when correlated with synchronization code signals or other components of broadcast TV signals, yield minimal sidelobes, produce large main peaks, and have minimal couplings to high frequency noise and low frequency disturbance signals. The present invention also provides a method and system for accurate position determination utilizing broadcast TV signals by employing reference signals with improved correlation characteristics of minimal sidelobes, minimal coupling to high frequency noise, minimal coupling to low frequency disturbance signals and a maximal main correlation peak.
