本文用指数相关模型对空间衰落相关的多输入多输出信道进行了建模,并基于此模型研究了A lam outi空时分组码结合波束成型的方案的比特错误概率,为便于比较,也研究了传统A lam outi空时分组码的比特错误概率,通过仿真得到了两种方案在不同相关信道中的误比特率性能。
In this paper, we use the exponential correlation model to model the multi-input and multi-output channels related to spatial fading, and based on this model, we study the bit error probability of A lam outi space-time block codes combined with beamforming schemes. For the sake of comparison, The bit error probability of the traditional A lam outi space-time block code is obtained by simulation. The bit error rate performance of the two schemes in different related channels is obtained through simulation.
