移动通信信道衰落特性模型的研究

利用超短波进行无线通信远距离移动通信传输时，仅需要不大的发射功率和适中的设备费用，且通信线路不易被摧毁．这些特点使其在无线远距离通信领域有广泛的发展前景．但由于其信道的特点，超短波无线通信存在可靠性低、质量差的弱点，无法适应越来越高的传输要求，作者分析了无线远距离通信信道的一些特性，并根据其路径损耗和多径效应引起的衰落，给出了无线远距离通信系统的通信信道模型．

Channel fading characteristic model of mobile communications

Moderate transmission power and reasonable equipment cost were only required by Long distance VHF wireless communication transmission, and the channel was difficult to be destroyed. These characteristics were extremely promising to be developed. However, because of the nature of its channel, it also had the deficiencies such as low reliability and poor performance to limit its application in ever- increasing communication demand. The characteristics of long distance wireless communication channel was presented, based on the channel fading characteristic model .
