Description: Diversity combining is specifically
targeted to counteract small scale fading. We will therefore use slow, flat, Rayleigh fading as our
model for the signal fluctuation. It must be emphasized that the Rayleigh model is the easiest and
most tractable. However, this model is not valid in all situations. The results we present here will
therefore be only “ballpark” figures, to illustrate the workings of diversity combining. Platform: |

Description: Clarke模型的提出代表了Rayleigh分布用于平坦小尺度衰落统计模型的开端。虽然因为其实现比较复杂,而更倾向于被认为是一种数学模型而非仿真模型,但所涉及到的Rayleigh衰落信道的概念是其后众多改进模型的基础-The Clarke model put forward on behalf of the beginning of the Rayleigh distribution for flat small-scale fading statistical model. Because its implementation is more complex, and more inclined to think that instead of the simulation model is a mathematical model, but involved in the Rayleigh fading channel concept is the basis of many subsequent improvement model Platform: |
