Time frequency representation of frequency hopping signals based on cyclic spectral correlation
Guo Jian-tao, Liu Liwei, Lin Wang · 2011
Time-Frequency (TF) representation is a precursory work on signal analysis. This paper addresses a novel method for TF representation of Frequency Hopping (FH) signals based on the relation between cyclic spectrum and TF representation. Differently from other known methods, the proposed method provides a simple valid time frequency representation of FH signals with the property of minimizing the effect of interferences while still offering an accurate TF resolution. Experiment result proved the validity and feasibility of the approach.
