用掺杂法产生具有一定互相关系数的瑞利衰落信道

The generation of correlated rayleigh fading channels by mixture

利用混合掺杂法将两个相互独立的白高斯随机序列加权混合后,能够与原序列构成互相关系数符合要求的两个瑞利衰落信道,供通信和雷达的算法仿真和系统模拟使用.该方法同时也适用于产生其他分布的相关信道,仿真结果证明了该方法的有效性.

By mixing two weighted independent white Gaussian random sequences, a pair of demanded correlated white Gaussian random sequences, the original and the new mixed sequences, can be generated to meet the occasions of correlated Rayleigh fading channels in wireless communication and radar systems. Furthermore, correlated channels with other pdf can also be generated by this means. Finally the validity of the method is proved by simulation result.
