A Novel Bit Synchronization Algorithm Design in Position System

Synchronization is one of the most important parts in the radio digital communication system, which can decide the performance of communication system. We design one novel bit synchronization algorithm, which can compute initial error within pre-set code cells´ period. In the low speed radio digital communication system such as specified position system, the synchronization algorithm proposed can ensure the system catching time predicable and stable. In simulation, we set the initial error compute period as 12 code cells in three SNR conditionings, no noise, -10dB SNR, and -20dB SNR. In all three conditions, this algorithm can compute correct initial error every time. The simulation results prove that this algorithm can compute valid initial error within pre-set code cells period, which is especially suited for bit synchronization in low speed radio digital communication system.
