QPSK调制后产生QPSK信号，QPSK信号分别通过AWGN信道、Rayleigh衰减信道和Rician衰减信道，分别通过QPSK解调出数字信号，通过输入与输出数字信号的对比计算出仿真过程中的传输误比率，并将其与各衰减信道的理论误比率进行对比(Generate QPSK signal QPSK modulation, QPSK signals through AWGN channel, Rayleigh fading channel and Rician fading channel, respectively, through the QPSK demodulation of digital signals by comparing input and output digital signals to calculate the simulation process of transmission error rate, and to compare with the theoretical error rate for each decay channel)

现今阵列应用中，宽带信号的处理越来越多。由同心圆阵组成的多圈圆形阵列在宽带信号处理上有更强的优势。和单圈均匀圆阵相比，同心多圈圆阵的嵌套设计阵列工作频率范围更宽，同时，灵活性增强。 (Nowadays array applications, the broadband signals in many more and more treatment. By the array composed of many concentric circular ring array of broadband signal processing at up there is more advantage. And single-lap compared to uniform circular array, circular array concentric circle many nested design frequency range of a broader array of work at the same time, enhance flexibility.)

Under the circumstances of pure lag in feedback control system and the imprecision of the controlled object model, the fuzzy logic and pure lag compensation theory is used to design a Fuzzy PI-Smith control system . By the Simulink toolbox and Fuzzy logic toolbox of MATLAB, the system has been simulated. The simulation results show that the Fuzzy PI-Smith system has faster response speed and smaller overshoot than the traditional PI-Smith system.The explicit formulation of Fuzzy PI-Smith system is derived, and it lay the basis for the practical application of control algorithms.strategy can do well in controlling the tail temperature. And the FuzzyPI-Smith system can get better dynamic characteristic and effectively overcome the problems by pure lag with the traditional ( Under the circumstances of pure lag in feedback control system and the imprecision of the controlled object model, the fuzzy logic and pure lag compensation theory is used to design a Fuzzy PI-Smith control system .
