| 摘 要： | 相关跳频(差分跳频)通信技术已成功地应用到短波(HF)通信中,但要想在超高频(UHF)频段应用该技术目前还存在诸多的困难.研究了在UHF频段对频域稀疏的宽频段信号结合稀疏分解的方法,提出了一种基于压缩采样理论的信号检测算法.仿真结果表明,该方法能成功用于跳频信号的频率检测和数据解调,并从中分离出所需的参数信息.

| Abstract: | Differential frequency hopping(DFH)has been successfully applied to the short wave(HF)communication,but there will be still some difficulties if we want to use it in ultra-high frequency(UHF)band.Based on the wide-band sparse frequency domain signal combined with sparse decomposition method in the UHF frequency band,this paper presents a signal detection method depending on the compressed sampling theory.Simulation results show that,this method can be successfully used for frequency detection of frequency h... |
