无线统计信道模型的一种分解表示法

影响无线移动通信系统性能的重要原因之一是无线信道特性,而从信道模拟实现或模拟仿真器层面上看,研究无线信道特性应重点关注不同信道间的共性和差异。通过对高斯、瑞利、莱斯等统计信道模型进行分解,从它们的共性出发,用误码率来衡量几种基本信道模型中的共性和差异分别对数据传输可靠性程度的影响,以建立具有共性的信道仿真模型。

Decomposition method for formulations of wireless statistic channel models

Characteristic of the radio channel is one of the most important factors which influence wireless mobile communication system''s performance. However, in the view of realization of channel simulation and channel emulator, more attention should be paid to the commons and differences between various kinds of channels in studying channel''s characteristics. To establish a common channel simulation model, this paper decomposes formulations of Gaussian, Raleigh and Rice channel model, gets their commons, and shows that the commons and differences would influence system''s performance, which are weighted with bit error rate (BER).Therefore, we can use these characteristics to establish simulation model in commons.
