程郁凡 %A 李少谦 %J 电子与信息学报 %D 2009 %I %X In this paper, a novel synchronization acquisition approach using the early-late gate for FFH/BFSK system is proposed, and it is based on frequency-PN sequence double pattern. Analytical and numerical results show the following advantages: the decision of threshold is more simple and accurate, and it overcomes the unreliableness of one-hop data demodulation, the unreliableness is caused by the not-alignment hop window of transmitter and receiver. The acquisition scheme can significantly improve the acquisition performance. When , where is the bit error rate and is the probability of synchronization acquisition. The analytical and numerical results are verified by a FFH testbed. %K Fast Frequency-Hopping(FFH) %K Synchronization acquisition %K Early-late gate %K Double pattern
