基于复小波包基函数调制的跳频多址通信系统

Complex wavelet packet basis function modulation based frequency-hopping multiple access communication system

  • 摘要: 该文给出了一种生成复数小波包基函数的方法,提出了一种基于复小波包基函数调制的跳频多址通信系统的模型,该系统在多径衰落时变信道下采用判决反馈均衡器接收的性能与基于实小波包基函数调制的同类系统相比有明显改善,且通过采用空间分集接收,可显著提高系统的误码率性能,该系统易于支持多速率话音和数据业务,具有频谱利用率高,抗单音干扰能力较强和保密性高等优点。
