介绍如何用matlab设计fir滤波器，很详细！！！！！！！！！！！！！！！！！(A great progress in the discipline of digital processing is the research on design method of digital filter. FIR digital filter plays a significant part in the processing of digital signal because it can realize linear phase so conveniently that the group delay doesn’t vary with frequency. In the modern electrical system, the FIR digital filter is applications for its good linear phase character.)

说明：  有限元方法编程matlab程序源代码，很好的(Finite element method matlab programming source code, well)

说明：  利亚普诺夫指数是混沌预测和混沌的重要参数，代码中给出利亚普诺夫指数和wolf算法(Liapunov index and the wolf chaos algorithm)

能利用发射端的多个天线各自独立發送信号，同时在接收端用多个天线接收並恢复原信息。(Can take advantage of multiple antenna transmitter sends separate signals, while the receiver with multiple antennas to receive and recover the original information.)

当空间调制（sm）系统中每个符号含有3bits信息(即3bit/s/Hz的频谱利用率)时我们选择：4根发送天线，BPSK调制方式和2根发送天线，4QAM调制方式进行比较。(When the spatial modulation (sm) system, each symbol comprising 3bits information (i.e. 3bit/s/Hz spectral efficiency) when we choose: four transmitting antennas, BPSK modulation method and two transmission antennas, 4QAM modulation for comparison.)

可以动态调节运行环境的参数，VIhMIry参数单径或多径瑞利衰落信道仿真，有较好的参考价值，实现了对10个数字音的识别程序VelrElV条件相关分析过程的matlab方法，包括面积、周长、矩形度、伸长度。( Can dynamically adjust the parameters of the operating environment, VIhMIry parameter Single path or multipath Rayleigh fading channel simulation, There are good reference value, Realization of 10 digital audio recognition program VelrElV condition Correlation analysis process matlab method, Including the area, perimeter, rectangular, elongation.)

说明：  利用matlab环境设计了DEA方法中CCR模型和CCGSS模型的计算程序(Environmental design using matlab CCR DEA model and the method of calculation procedure CCGSS model)
