| 摘 要： | 采用DSP技术产生混沌信号,再量化、编码成二值序列,用来调制UWB脉冲信号.充分利用DSP数据处理的快速、灵活的优点,也能满足UWB信号传输速率快的特点.实验最后给出UWB通信系统在TH-PPM方式下,采用混沌序列调制UWB信号所得到的功率谱结果,并和未采用混沌序列调制的功率谱结果进行比较.

| Abstract: | Chaotic sequences were generated, quantized and coded into binary sequences which were used for modulation of UWB signal based on DSP technology. Good merits of rapidness and agility were fully utilized in DSP based data processing. It can also satisfy high speed of UWB signal. In the end, under TH-PPM scheme of UWB communication, experiment was made to give results of the power spectrum of chaotic modulated UWB signal. The results of power spectrum of UWB signal that were not chaotic modulated were also given by comparison. |
