To address the direct sequence spread spectrum system, the number of transceivers in the initial frequency of the capture problem, a transformation through the DFT, in the frequency domain for parabolic interpolation computing frequency offset estimation algorithms. The algorithm can be adapted to low signal to noise ratio, broadband rates offset the scope of bad communications environment and unexpected modes of communication, and the algorithm complexity low. The algorithm has been realized in the FPGA.
