ofdm程序

本程序主要实现LZ77的编码以及解码，并且对压缩率进行了说明，简单明了(The main achievement of LZ77 encoding process and decoding, and are described on the compression ratio, simple)

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )

语音信号处理课设内容，包括采集和处理语音信号，用的软件为Matlab(Speech signal processing course based content, including the collection and processing of voice signals, with the software Matlab)

BPSK调制下的2发一收空时分组码程序，本程序是对两发一收情况下采用空时分组码的性能分析，星座映射采用的是BPSK映射，接收天线上的接收信噪比，在仿真的过程中把接收信号的功率归一化为1(BPSK modulation issued a collection of two space-time block code program)
