The existing frequency hopping (FH) signal analysis methods have the disadvantages of poor time-frequency resolution and low noise suppression ability. Because of the large bandwidth feature of the FH signal, the time-frequency analysis methods are confined to the high sampling rate. In order to solve these problems, the compressive sensing (CS) is applied to the time-frequency analysis of FH signals...
The existing multi-tone jamming suppression algorithms for direct sequence spread spectrum (DSSS) communications are confined to the high sampling rate. The compressive sensing (CS) was applied to solve the problem. Firstly, the DSSS signal and multi-tone jamming sparse dictionary was built, the multi-tone jamming suppression algorithm used in compressed domain was designed. Secondly, due to the difficulty...
