采用直接法实现实信号输出信道化发射机matlab仿真程序:可清楚地看出输入的基带信号被分别调制到了相应的频带上，并且输入的各路基带信号的频谱结构可以很明显地在输出的频谱中体现出来-Using the direct method to achieve real signal output channel of the transmitter matlab simulation program: You can clearly see that the input base-band signal

Recognition of visual patterns and characters are independent of position, size, and orientation in the visual field has been the goal of much recent research. The method presented in this paper meets all these condition. An off-line signature matchi

利用MAXPLUS作为仿真工具，用VHDL语言编程，采用频率键控法实现3FSK调制。对输入的系统时钟分别进行2分频，4分频和8分频得到这3种频率。通过对数字基带信号进行双二进制编码得到3个电平值，把它们作为三选一开关，来分别选择不同的频率值、选择不同的信号，从而实现3FSK调制。-As a simulation tool used MAXPLUS using VHDL language programming, using frequency shift keying modulation me
