同步技術是跳頻通信系統(tǒng)的關鍵技術之一，尤其是在快速跳頻通信系統(tǒng)中，常規(guī)跳頻通信通過同步字頭攜帶相關碼的方法來實現(xiàn)同步，但對于快跳頻來說，由于是一跳或者多跳傳輸一個調(diào)制符號，難以攜帶相關碼。對此引入雙跳頻圖案方法，提出了一種適用于快速跳頻通信系統(tǒng)的同步方案。采用短碼攜帶同步信息，克服了快速跳頻難以攜帶相關碼的困難。分析了同步性能，仿真結果表明該方案同步時間短、虛警概率低、捕獲概率高，同步性能可靠。 Abstract: Synchronization is one of the key techniques to frequency-HOPPING communication system， especially in the fast frequency HOPPING communication system. In conventional frequency HOPPING communication systems， synchronization can be achieved by synchronization-head which can be used to carry the synchronization information， but for the fast frequency HOPPING， Because modulation symbol is transmitted by per hop or multi-hop， it is difficult to carry the correlation code. For the limitation of fast frequency HOPPING in carrying correlation code， a fast frequency-HOPPING synchronization scheme with two HOPPING patterns is proposed. The synchronization information is carried by short code， which overcomes the difficulty of correlation code transmission in fast frequency-HOPPING. The performance of the scheme is analyzed， and simulation results show that the scheme has the advantages of shorter synchronization time， lower probability of false alarm， higher probability of capture and more reliable of synchronization.
