Receiving and Processing Method for Frequency-Hopping Signals based on Compressed Sensing

为了有效解决军事卫星通信和航天测控通信系统在跳频信号的超宽带、超高频、高码率、高采样率等方面处理压力的问题,通过对压缩感知原理关键技术问题和传统跳频信号处理方法国内外现状的研究,提出了基于压缩感知的跳频信号接收处理方案。结合跳频信号的内部结构特性,考虑跳频图案和动态多普勒引起的频偏,从跳频信号的稀疏性分析和模型的建立出发,对跳频信号稀疏分解表示、数字域模拟域压缩采样、压缩域跳频信号相关解调处理三个方面进行简要论述,并进行了总结展望。

To effectively solve the processing pressure of UWB communication, ultra high frequency, high code rate and high sampling rate of FH in the military satellite communications and Aerospace TP ＆ C communication system, a FH receiving and processing scheme based on compressed sensing is proposed through the research on the key technologies of the compressed sensing theory and the traditional processing methods of FH both at home and abroad. In combination with the characteristics of FH internal structure, and consideration of the frequency offset caused by FH pattern and dynamic doppler, this paper, starting from the sparsity analysis and model establishment of FH , briefly discusses and forecasts the three aspects including the sparse decomposition of FH, the compressive sampling in the digital and simulation domain, and the correlation demodulation processing of the FH in the compressed domain.
