摘　　要：分析了空间相关Rayleigh衰落信道下采用空时分组编码的MIMO通信系统的误符号率。利用Laplace变换推导了空时分组编码系统在接收端信噪比的概率密度函数,得出了由基本初等函数表示的线性调制下空时分组编码系统误符号率的闭合表达式。仿真结果证明了性能分析的有效性。The symbol error rate of space-time block coding in MIMO correlated Rayleigh fading channels is analyzed. The probability density function of the received signal to noise ratio is derived by Laplace transform. The closed-form symbol error rate expressions of space-time block coding （STBC） coded system are given for linear modulations in the form of basic elementary functions. Simulation results demonstrate the validity of the performance analysis.
