串口发送接收数据。可配置端口，波特率等。 发送可选择ASCII方式或HEX方式。 中断方式接收数据。 可以通过ADC和MCU可以把数据通过 串口直接发送到PC上让MATLAB分析(receiving data. Configurable ports, baud rate, and so on. Send option HEX or ASCII mode. Interrupt receiving data. Through the MCU and ADC data can be sent directly through the serial port to the PC for analysis of MATLAB)

说明：  滤波在 世纪 年代初一经提出，立即受到工程界，特别是空间技术和航空界的高度重 视。应用 滤波算法进行卫星轨道精密确定，必须首先构造可靠的卫星动力学模型和可靠的观 测模型以及合理的估计方法。(Filter was put forth in the 1750s and started immediately subject to the engineering sector, especially in space technology and attaches great importance to the aviation community. The application filtering algorithm precision determination of satellite orbit must first construct the the reliable satellite dynamics model and observation model, and the reasonable estimation method.)

fft算法matlab实现，可直接运行，对比给定波形和经过fft后的波形效果(fft algorithm matlab realize, can be directly run, compared to a given waveform and waveform effects after fft)

说明：  一阶倒立摆写状态空间方程，在输入量的控制下，显示最终小车图像(The first-order inverted pendulum writes the state space equation and displays the final car image under the control of the input)

编写一个含QAM传输的发送和接收模块 1)分别采用复基带仿真和实带通仿真两种形式 a) 实带通仿真时, 载波频率为符号率的4倍 b)发端采用滚降系数0.5的根号升余弦滤波器 2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样 3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声) 统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比 (Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)
