7. 单径瑞利信道中的两发一收STBC： (1) 分析误码率的理论性能，画出比特信噪比与误码率的关系曲线。 (2) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。(7. Two outgoing and one outgoing STBC in single-path Rayleigh channel: (1) analyze the theoretical

根据蒙特卡罗仿真原理,对QPSK及QDPSK进行误码率仿真分析里面有7个程序(According to Monte Carlo simulation principle, there are 7 programs in BER simulation analysis of QPSK and QDPSK.)

分析ADC的有效位数（ENOB）对QPSK误码率性能的影响，也就是分析量化噪声对QPSK性能的影响(The effect of ENOB of ADC on the BER performance of QPSK is analyzed. That is to say, the influence of quantization noise on the performance of QPSK is analyzed.)
