| 摘 要： | 在已有发送参考脉冲超宽带系统基础上，针对拓展距离超宽带应用需求，借鉴雷达信号处理中的去斜脉冲压缩方法，提出了一种基于有源频谱压缩结构的正交码发送参考chirp超宽带系统. 数学推导和性能仿真结果表明，该系统兼具发送参考结构和chirp通信系统的优势，不需要模拟匹配滤波器件和高速模数转换器件，更有利于系统的小型化、低功耗和集成化设计.

| Abstract: | Based on the transmitted reference impulse radio ultra wideband (IR UWB) system, a new code orthogonalized transmitted reference chirp UWB system is proposed to meet the needs of UWB application with increasing transmission distance. Referring to the de chirp methods in radar system, it designs an active spectrum compressed structure for the receiver. Analysis and simulation show that this system has both the advantages of transmitted reference IR UWB systems and chirp UWB systems. Furthermore, the analog matched filter and high speed analog to digital converter are not required, but facilitate system miniaturization, low power consumption and integration design. |
