The Hopping Communication System Research Based On Differential Frequency Hopping And RS Sequence Wide Interval Frequency

Spread spectrum communication as a result of its strong anti-jamming, privacy advantages earliest military and civilian Bluetooth communication is widely used. Frequency hopping spread spectrum communication is a multi-class means of communication among the most talked about, its principle is according to a set of pseudo-random sequence randomized which controlled carrier frequency hopping communication transceiver to achieve mutual communication. Frequency hopping communication is provided with the characteristics that are interference, fading, anti-interception, CDMA and frequency bands shared, so the modern military and civilian communications and mobile communications have wide applications.The structure of hopping sequence is one of most important the key technologies in frequency hopping communication. With good randomness and correlation of frequency hopping communication system play a decisive role. The design of frequency hopping sequence has been hopping communication research focus, this paper put forward two generated hopping algorithms. One kind of based on RS sequence nonlinear mode interval method, one kind of based on improved Logistic and Tent Mapping of differential frequency hopping. By Matlab simulate results show that the sequence compared to the original sequence with better meet hopping sequence indicators, such as Hamming correlation, balance, hopping interval; Using the above algorithm produces wide interval RS frequency hopping sequence set up frequency hopping communication system and simulate various communication phase of using Matlab.which show that the use of the frequency hopping sequence can well meet the requirements of frequency hopping system. Finally build the hardware platform and implemented on the sequence via DSP and frequency hopping communication system.
