Ying Guo · Signal Processing · 2009
A novel algorithm is presented for blind parameter estimation of frequency hopping signals.According to the structure of frequency hopping signals,the three-parameter frequency-time atom is obtained from the unit windowed sine function.On the base of these,a atomic decomposition based parameter estimation algorithm of frequency hopping signal is developed.Using this algorithm,the parameter of frequency hopping signals i.e.as hop duration,hop timing and hopping frequencies can be estimated without any priori knowledge.Simulation results demonstrate that the method is effective and efficient.
