Frequency Hopping Pattern and Synchronization based on Hopping Spread Spectrum Communication

The frequency hopping pattern and synchronization technology are the cores of frequency hopping spread spectrum communication. The current hopping patterns are very complex and hard to implement. In this paper, a frequency hopping pattern with very long period is designed based on m-sequence, which is suitable for hardware implementation. Besides, as for the current synchronization technology, it performs poorly when the environment is of strong interference and with high dynamic. In this paper, a synchronization scheme based on the Fast Fourier Transformation algorithm is given under the concrete frequency hopping spread spectrum communication system, and is suitable for high dynamic environments and low signal-to-noise ratio. Finally, on the basis of simulation on MATLAB under the above communication system, properties of the synchronization scheme are analyzed.
