摘要

中文摘要: 为了比较各种基于谐波信号叠加(SoS)瑞利衰落信道模型的复杂度和性能，推导确定型SoS模型的二阶统计量和均方误差的数学表达式，并指出该模型互相关函数的均方误差为非零常数，证明随机型SoS模型最佳入射角需要满足的条件，并与常见取值方法进行了比较。仿真结果表明，确定型模型由于入射角固定运算量较低，正交分量之间以及多径信道之间的相关性强；而随机型模型通过选取适当的入射角，可以获得良好的统计特性。

Abstract

Abstract:In order to compare the complexity and performance of Sum-of-sinusoids (SoS) models for uncorrected Rayleigh fading channels

the second-order statistical formula for deterministic SoS model was derived

which showed that the variance of cross-correlation was not zero. Then

the requirements of signal′s angle of arrival(AoA) for statistical models were proved

which was used to compare with different selections. Simulation results showed that deterministic model has lower complexity but poor performance of independence between multiple channels

however statistical model has ideal statistical properties with proper AoA.
