程序的主要功能是做了一定范围的信噪比下，对每个信噪比：随机信号QPSK调制； 根据Alamouti方案的矩阵进行编码；发送信号经过瑞利信道和加入高斯白噪声； 接收信号采用最大比合并的方法；最后对合并信号进行最大似然判决并求误符号率。 结果表明10^-3对应大约12->13dB(Procedure main function is to do a certain range of SNR for each signal to noise ratio: random signal QPSK modulation program in accordance with Alamouti coding matrix send signals through Rayleigh channel and adding Gaussian white noise received signal using maximal-ratio combining method Finally the combined signal and the maximum likelihood decision for symbol error rate. The results showed that about 10 ^-3 corresponds to 12-> 13dB)

前人提出的众多发酵动力学模型的基础上，结合工业乙醇连续发酵的实际情况，首先对经典的流加半经验半理论模型进行动态和稳态仿真，之后为了与实际生产过程联系更加紧密，逐步将温度，气体排放等因素考虑到模型中去，进行综合性仿真。最后再结合GUI技术，以动力学模型为核心，以人机界面友好为目标，制作乙醇连续发酵仿真软件，将脚本语言编程技术和模块化仿真技术结合起来，建立起工业乙醇发酵的仿真平台。(Made numerous predecessors fermentation kinetics model based on the combination of industrial ethanol continuous fermentation of the actual situation, the first of the classic semi-fed semi-empirical model for dynamic and steady-state simulation, after which the actual production process for closer ties, gradual temperature, gas emissions and other factors into the model to carry out a comprehensive simulation. Finally, combining GUI technology to kinetic model as the core, friendly interface for the target, producing continuous ethanol fermentation simulation software, the script language programming techniques and modular simulation technology combine to build industrial ethanol fermentation simulation platform.)
