A new interleaving method in the adaptive frequency hopping system

A new interleaving method for adaptive frequency hopping system is proposed, which uses the prime code to control information sequence's order at the transmitter and change the order back at the receiver. The new interleaving method possesses the features of low correlation coefficient, low interleaving latency, small storage capacity and flexible matrix realization, which reaches the relative optimal performance metrics of interleaving. Monte Carlo simulations show that in an adaptive frequency hopping communication system simulation platform the new interleaving method can improve the performance of anti-consecutive errors beyond the error correction capability of channel coding and has the advantages of easy implementation, low interleaving delay and small calculation amount compared with the block interleaving and pseudo-random interleaving on the premise of meeting the specific error rate performance. Moreover, our new interleaving method has a better anti-jamming performance in the adaptive frequency hopping system. The anti-jamming performance of our interleaving method is better than block interleaving and is a bit worse than pseudo-random interleaving method.
