-
摘要: 該文首先介紹了采用超寬帶(UWB)信號實現(xiàn)擴頻通信的工作原理,然后分析了接收信號處理方式,并從理論上推導出表征系統(tǒng)性能的誤比特率和最大接入用戶數(shù),最后進行了數(shù)值仿真計算,研究結果表明,UWB通信是一項很有發(fā)展?jié)摿Φ母咚贌o線接入技術。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.
