不同衰落下的并行信道建模与容量分析

无线信道的分析与建模是无线通信研究的基础的工作,信号在传输过程中会受到不同衰落环境的影响,例如频率选择性衰落、时间选择性衰落和空间选择性衰落。为了分析无线传播环境在这三种衰落条件下的信道特性,分别对三种衰落信道进行并行信道建模,在此基础上将注水原理分别应用于这三种衰落信道中,即分别在频率、时间和空间上进行最佳功率分配,只对信道状况良好的子信道分配功率,最后得到不同衰落信道下的信道容量。

Parallel Channel Modeling and Capacity Analysis in Different Fading Environment

The analysis and modeling of wireless channel is a fundamental work for research on the wireless communication.Signals pass through different fading environments during their transmission,such as frequency selective fading,time selective fading and space selective fading.For the purpose to analyze the channel characteristics of the wireless propagation environment in the three fading conditions,the parallel channel modeling for the three fading channels was performed respectively,and the waterfilling princi...
