摘要
介绍了超宽带(UWB)无线通信的技术及特点,与传统窄带无线系统进行了性能比较,指出了超宽带无线通信四大关键技术是:超宽带无线通信脉冲信号的波形设计;超宽带无线通信脉冲信号编码与调制方式;超宽带无线通信信号的检测;超宽带无线通信系统中的同步捕获技术;分析了超宽带无线通信系统军用的潜在市场,最后阐述了SAW宽带信号处理技术在UWB通信系统中的应用。
The ultra-wideband wireless communication technology and its characteristics have been introduced in this paper. A comparison of the performance between the traditional narrowband wireless communication system and the ultra-wideband wireless communication system has been made. The four key techniques of the ultra-wideband wireless communication, that is, the waveform design of the ultra-wideband wireless communication pulse signal, the coding and modulating system of the ultra-wideband wireless communication pulse signal, the measurement of the ultra-wideband wireless communication and the synchronization acquisition technique in the ultra-wideband wireless communication system has been presented. The potential military market of the ultra-wideband wireless communication system has been analyzed. The application of SAW wideband signal processing technology to the ultra-wideband wireless communication system has also been presented in this paper.
