摘    要:快速捕获技术是高速跳频系统中的关键技术,传统的等待搜索法具有一定的局限性.为了提高高速跳频系统的同步性能,在高速跳频系统中采用扫描和多次驻留检测的捕获方案,将多次驻留检测过程建模为马尔可夫模型,并通过在Matlab7.0/simulink环境中进行仿真,得到了捕获检测概率和捕获时间的仿真结果.仿真表明,经过70 ms后,系统达到同步;采用该方案,能够缩短捕获时间,提高系统性能.

关 键 词:扩频通信  高速快速跳频  扫描搜索  驻留检测  马尔可夫模型

Abstract:Fast capture is one of the key technologies in high-speed fast frequency-hopped (FFH) system. Due to the traditional waiting search strategy features limitations,thus to enhance the synchronous performance of high-speed FFH system,the capture strategy combining scanning and multiple dwell detecting is adopted in the system; and the multiple dwell detecting process is modeled as a Markov model,and through operational simulation under Matlab7.0/Simulink environment,the simulated result for capture detecting p...
Keywords:Spread spectrum communication High-speed fast frequency-hopped Scanning search Dwell detecting Markov model
