This paper introduces an adaptive hybrid SFH/TSS/DPSK spread spectrum system with separated interference detector. The basic working principles and architecture of the system are explained. The theoretic BER (bit error rate) of the system is estimated and compared to the classic DS/BPSK system in the presence of interference. Simulation results show that the anti-jamming capability of the adaptive hybrid spectrum spread system is better than DSSS in the environment concerned.
