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。
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 hopping signals and data demodulation,and obtain the required parameter information.
