“…The obtained evaluation and experiment results using FFT show that this approach performs high accuracy and less complexity. By the mean of three-line method also avoids the disadvantage in [5] and [6], which performs significantly deteriorated in some special position as frequency offset. The flow chart of algorithm is given as follow.…”

“…Aimed at MPSk this paper established the signal model: the channel is an additive white Gaussian noise channel; assuming that perfect symbol synchronization has been achieved; the inter-symbol interference is not considered. Suppose the received BPSK signal is (2 ) ( ) e ( ) [5]. In practical applications the umber of data is not large enough.…”

In order to actualize the fast synchronization of carrier in high dynamic, A New union carrier synchronization algorithm based on FFT and PLL (Phase Locked Loop) is proposed. The basic idea is that firstly get a coarse estimation by using the peak of a period gram and then gain an accurate estimation by using a new interpolation formula about the two lines beside the pea. Next, using the frequency as guide frequency, to control the frequency of the sine signal produced by the NCO (Numerically Controlled Oscillator). And finally achieve the goal of carrier synchronization through the adaptive algorithm of the PLL. With the method of real-time and precise estimation of carrier, it can reduce the tracking time in low signal-to-noise rate and high dynamic condition. The results show that it can effectively achieve the expectations of carrier quickly capture and carrier accurate tracking.
