针对目前常见的FDMA、TDMA、CDMA,介绍了一种新的基于PR-QMF滤波器组的扩频技术.其扩频信号由合成滤波器产生,而分析滤波器则执行解扩过程.文章中简要介绍了该系统模型,并对其性能在AWGN及有正弦干扰情况下利用蒙特卡洛仿真,从而得出结论
A new, PR-QMF based, spread spectrum technique is introduced. The transmitted signal is generated by a synthesis filter bank and the demodulation process is performed by an analysis filter bank. The framework of this system is described and Monte Carlo simulation is used to determine the bit error rate(BER) performance with AWGN and sinusoidal jammer.
