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

  • 摘要: 該文給出了一種生成復(fù)數(shù)小波包基函數(shù)的方法,提出了一種基于復(fù)小波包基函數(shù)調(diào)制的跳頻多址通信系統(tǒng)的模型,該系統(tǒng)在多徑衰落時(shí)變信道下采用判決反饋均衡器接收的性能與基于實(shí)小波包基函數(shù)調(diào)制的同類(lèi)系統(tǒng)相比有明顯改善,且通過(guò)采用空間分集接收,可顯著提高系統(tǒng)的誤碼率性能,該系統(tǒng)易于支持多速率話音和數(shù)據(jù)業(yè)務(wù),具有頻譜利用率高,抗單音干擾能力較強(qiáng)和保密性高等優(yōu)點(diǎn)。
    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.
