HDB3 codification, a matlab program that make a hdb3 codification

The file is a simulation based on simulink about ofdm system.

these matlab files are different modulation techniques in communication

用monte carlo仿真估计并画出利用反极性信号的二进制通信系统的差错概率性能。(Using Monte Carlo simulation and draw the error probability performance by using the binary communication system reverse polarity signal..)

说明：  这里实现的卷积码译码器可实现（n,1,K）的卷积译码，即一个输入码元，n个输出码元，编码器的约束长度为K，采用函数的默认值将实现（2,1,7）的卷积译码。译码方法为维特比硬判决译码，且译码开始状态假定为全零状态。(Here to realize convolutional code decoder can realize (n, 1, K) convolutional decoding, namely an input element, n output element, encoder constraint length is K, takes the default value of function, achieve the convolutional decoding,1,7 (2). Decoding method for decoding victor than hard decisions, and decoding the start state assumed to zero state.)

qdpsk调制主要是帮助那些需要代码的朋友们，这些代码仅作参考，如有疑问请留言！！！谢谢(qdpsk modulation is mainly to help friends who need the code, the code is only for reference, if any questions please leave a message! ! ! Thank you)

说明：  matlab的基础应用,主要是基础部芬的学习笔记,大家看看有没有用!(Matlab based applications, the Department of fun is the foundation of learning Notes, we see no use!)

采用功率谱方式并用AR线性滤波方法生成脉动风速时程数据，能用于结构风载荷的计算。(Using power spectrum and AR linear filtering method to generate fluctuating wind speed time series data, can be used in structure wind load calculation.)
