Abstract In this paper, the approach to produce the complex wavelet packet basis function is given. A complex wavelet packet function based frequency-hopping multiple access communication system, which employs antenna diversity and decision feedback equalization, is proposed. The simulation results show that the new multiple access system outperforms the analogy system based on real wavelet packet basis function modulation. In addition, it has high spectrum efficiency, high security and good narrow band interference rejection capability. Furthermore, the developed system is also easy to support multirate voice and date services.
