Abstract

The carrier frequency offset is a common problem in communication systems, but in most case, phase-locked loop (PLL) can only track small frequency shift, so an estimation of initial frequency offset is necessary for CPM synchronization. In coded multi-h CPM system, it is a convenient method to use the information of frame header for frequency estimation. In this paper, we combine the pulse-pair technique and fast Fourier transform (FFT) calculating method for our purpose. According to the simulation results, it can achieve accurate estimation for comparative great frequency offset and perform steady even in low signal-to-noise ratios (SNRs).
