A High Sensitivity GNSS Signal Bit Synchronization Algorithm Based on Matched Filtering
Ming Yin · Microelectronics & Computer · 2011
A new bit synchronization algorithm based on matched filtering is presented applicable to this signal structure.It can significantly improve the sensitivity of bit synchronization.When spending 2s to synchronize the signal with NH(20) second code signal structure,simulation results show that the bit synchronization sensitivity can reach 12dB-Hz with false bit synchronization probability of 1e-3.
