GFDM

主要介绍ofdm中各种信道估计方法，包含一维和二维信道估计方法(Introduces the OFDM channel estimation in a variety of methods, including the one-dimensional and two-dimensional channel estimation methods)

There were downloaded documents wich can be very useful for those who exploring Wireless Sensor Networks. There given all the information and scripts to creat or build the model you need.

Matlab入门级OFDM仿真，包括每个步骤的波形，星座图，频谱等 含循环前后缀，时域加窗等，适合刚接触OFDM的学习 (Matlab entry-level OFDM simulation, including each step of the waveform, constellation diagram, spectrum including cycles before the suffix, such as time-domain windowing for OFDM new to the learning)

说明：  产生数字基带信号，加入AWGN高斯白噪声在信道中传输，检测出原始基带信号，并绘制理论和仿真误码率曲线(The digital baseband signal is generated and transmitted in the channel with AWGN white Gaussian noise. The original baseband signal is detected and the theoretical and simulation BER curves are drawn)

说明：  载波相位平滑伪距，针对伪距的异常情况，利用载波相位进行平滑处理(Carrier phase smoothing pseudo-distance)

本代码描述了OFDM/OQAM的基本仿真框架，AWGN信道下的ber性能。OFDM/OQAM 是一种很好的多载波系统。(This code describes the basic simulation framework for OFDM/OQAM ber performance in the AWGN channel. OFDM/OQAM is a good multi-carrier system.)

turbo均衡的一种算法修改的MMSE算法对深刻理解TE很与帮助。(turbo balanced an algorithm modified MMSE algorithm is with a deep understanding of TE help.)

一种降低正交频分复用信号峰均功率比的方法--压缩扩展变换()

基于stm32的心电滤波算法，用MATLAB说明(STM32 based ECG filtering algorithm, illustrated by MATLAB)

说明：  4. 试说明卷积编解码的工作原理： (1) 使用Simulink仿真卷积编码，并用Viterbi译码的方法进行解码，其中的编码、译码全部是自己编写代码(S-Function方式)，不是调用Simulink的已有编码、译码函数。 (2) 请在加性白高斯噪声信道中，画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec: (1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink. (2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)
