Spectrum-Hole-Detection
- 本文首先介绍了认知无线电的基本概念,对认知无线电在WRAN系统、UWB系统及WLAN系统等领域的应用分别进行了讨论。在此基础上,针对实现认知无线电的关键技术从理论上进行了探索,分析了影响认知网络正常工作的相关因素及认知网络对授权用户正常工作所形成的干扰。从理论上推导了在实现认知无线电系统所必须面对的弱信号低噪声比恶劣环境下,信号检测的相关方法和技术,并进行了数字滤波器的算法分析,指出了窗函数的选择原则。-The development of the wireless business resul

ETSI-Ultra-Wide-Band
- Ultra Wide Band (UWB) is a technology for the transmission of data using techniques which cause a spreading of the radio energy over a very wide frequency band, with a very low power spectral density. The low power spectral density limits the interfe
4GG
- The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB), and Millimeter wireless. Data rate of 20mbps is employed. Mobile speed will be up to 200km/hr. The high performance is achieved by the use of long te
