不同信道下的超宽带无线通信系统Simulink仿真研究

建立了无多径AWGN信道、IEEE802.15.3a多径信道下的两种UWB通信系统仿真模型,给出了发射、信道、接收三个部分的仿真波形,实现了在高斯白噪声信道下点对点的通信,并表征了TH-PPM和TH-PAM两种调制方式。仿真结果表明:该模型能够很好地反映UWB信道的特征参数,可用于UWB的物理信道的研究分析,方便地用在UWB系统的设计研究。

Simulink Simulation Study of UWB Wireless Communication System in Different Channels

Two communication system models of AWGN channel and IEEE 802.15.3a channel were constructed and three kinds of simulation waves which contain launcher, channel, receiver were given, the point-to-point communication in AWGN channel of TH-PPM and TH-PAM were showed. The simulation results show that the model reflects well to the measured results of UWB channel and it can be used to simulate the parameters of the physical channel.
