| 摘 要： | 文章对短波高速串行信号的相关检测进行分析.首先分析了固定门限判决和自适应门限判决,在此基础上综合二者提出固定门限与自适应门限相结合的混合门限判决方法.经过仿真实验表明,该混合门限算法综合了固定门限与自适应门限的优点,在短波信道下低信噪比时综合性能有较大改善.

| Abstract: | In this paper,the threshold control scheme for the acquisition of the high data rate high frequency(HF) serial signals is analyzed.Based on the discussion of fixed threshold scheme and the adaptive threshold scheme,a mixed threshold control scheme is proposed,which integrates the advantages of both the fixed and adaptive threshold control scheme.The simulation indicates that when the signal-to-noise ratio(SNR) is low,the mixed scheme is improved in both false alarm and correct acquisition under HF channel. |
