对在突发通信中基于噪声功率和基于信号功率的自适应门限信号检测方法进行研究,提出了在滑动窗口中进行比较判决的自适应门限检测方法,用多个采样点进行比较判决以取得最优的同步信号。仿真比较不同情况下的系统性能,结果表明改进方案能得到精确的系统同步信号,低信噪比时,基于噪声功率的自适应检测方法检测概率较大。 In the burst communication based on the noise power and signal power based on the threshold signal detection method to study the proposed sliding window in the comparative judgment of the adaptive threshold detection method, with multiple sampling points to make the most judgments to obtain the most Excellent synchronization signal. The simulation results show that the improved scheme can get accurate system synchronization signal and the detection probability of adaptive detection based on noise power is high when signal to noise ratio is low.
