摘要
本文通过对具有相同能量和相同脉宽的不同 UWB( Ultra Wide Band)脉冲信号在脉位调制 ( PPM,Pulse Position Modulation)和脉幅调制 ( PAM,Pulse Amplitude Modulation)方式下的抗噪声性能的理论分析与仿真对比 ,研究了在 AWGN( Additive White Gaussian Noise,加性高斯白噪声 )条件下 。
This paper is based on the theoretical analysis and simulation comparisons of the anti-noise performance of different UWB (Ultra Wide Band) pulse signals which keep the same pulse energy and pulse width in the different modulation means of PPM and PAM, we study the relationship between the choices of different pulse shapes and the system performance on the conditions of AWGN and different modulation means.
