| 摘 要： | 超宽带无线通信是指采用了一种相对中心频率而具有较大带宽的信号（通常指分数带宽大于25%的信号）来传输信息的通信方式.在充分考虑超宽带信号在自由空间和密集多径环境中传输特性的基础上,基于最优化方法分析了二元情况下的超宽带通信信号的设计思想,并给出了归一化平方Euclidean距离、误码率与时移参数关系的仿真结果.

| Abstract: | Ultra-wide-band(UWB) wireless communication utilizes signal with a very wide bandwidth around a relatively low center frequency to transmit information.The authors analize the signal design of UWB when it was formutated in two-element condition based on the optimal method over the free-space and mulitipath channel. |
| |
| Keywords: | ultra-wide-band communication signal design optimal principle multipath channel |
