LTE上行链路仿真C代码,包含CRC添加、信道编码、信号调制、基带信号等~(LTE simulation for the uplink of C code, including CRC added, channel coding, modulation, baseband signal. )

轨道不平顺的matlab代码，包括竖向和水平向两个代码文件。读入的为要求轨道长度，时间，时间间隔。简单(Matlab code track irregularities, including vertical and horizontal to the two code file. Read for requirements of rail length, time, time interval. simple)

用matlab对基于最小错误率的Bayes分类器进行仿真，编写了相应的程序.(Using matlab based on the Bayes minimum error rate classifier simulation, the preparation of the corresponding program.)

利用低通、带阻FIR以及IIR技术对心电图上附加的白噪声、高斯噪声等进行滤波还原操作（内附心电图数值样品）。(We use low-pass, band stop FIR and IIR technology to filter and restore the additional white noise and Gauss noise on ECG.)

OFDM系统的仿真代码MATLAB环境下(OFDM system simulation environment MATLAB code)

说明：  络检波法，也可以用同步解调法，现在我们来使用同步解调法，即将已调信号和一个与载波信号同频率的信号相乘，在通过一个理想低通滤波器就可以得到原始信号(Envelope detection method, you can also use synchronous demodulation method, and now we use synchronous demodulation method, is about modulated signal and a signal is multiplied with the same frequency of the carrier signal, through an ideal low-pass filter can get the original signal)

这个程序再matlab2012b版本上调试成功，以前在毕业设计的时候在网上找到的资料，希望对大家有用，基于线性预测系数(LPC)的语音信号重构。给出了完整的LPC matlab程序，包括语音信号采集，LP预测系数，阶数的选择以及预测结果误差曲线。（很好用）(This version of the program and then on the successful commissioning matlab2012b information previously graduation when found online, we want to be useful, based on linear prediction coefficient (LPC) voice signal reconstruction. Given a complete LPC matlab procedures, including voice signal acquisition, LP prediction coefficients, select the order and the prediction error curve. (Well used))

改程序对一个信号分别进行BPSK、PCM、PM三种处理。(Change procedures for a signal, respectively, BPSK, PCM, PM, three kinds of processing.)

通过对语音信号的采集和AD50数模转换实现语音信号的处理，并通过C54试验台可以很好的实现语音再现。FIR数据滤波数据需要通过MATLAB来实现。(Through the acquisition and AD50 voice signal digital-analog conversion of voice signal processing, and through the C54 test bed can be a very good voice reproduction. FIR data filtering data to achieve through MATLAB.)
