Comparison of log normal shadowing and coding effects in a diversity combining DS/CDMA Cellular system

A major issue with ad-hoc networks is energy consumption since nodes are usually mobile and battery-operated. In this project we compared the performance of ad-hoc routing protocols in a network where each participating mobile node has a given

频谱感知技术是认知无线电技术里最关键和最具挑战性的技术-Spectrum sensing is a key technology in Cognitive Radio (CR). It provides the CR system with available vacant channels list by sensing the spectrum environment over a wide frequency band. However, local sensing by
