UWB扩频通信技术研究
STUDY ON UWB SPREAD SPECTRUM COMMUNICATION TECHNIQUE
【摘要】 该文首先介绍了采用超宽带(UWB)信号实现扩频通信的工作原理,然后分析了接收信号处理方式,并从理论上推导出表征系统性能的误比特率和最大接入用户数,最后进行了数值仿真计算,研究结果表明,UWB通信是一项很有发展潜力的高速无线接入技术。
【Abstract】 In this paper, the operating principle of UWB spread spectrum communication technique is described first, then the receiver signal processing is analyzed, the multiple access performance: BER and the number of users that system can support is evaluated. The numerical results is presented. These studies indicate that UWB has potential capability in the field of high speed wireless access in dense multipath environments.
