教材simulation and software radio for mobile communications中所讲的实例程序源码(Materials simulation and software radio for mobile communications in the program source code examples about)

可以利用c#读取segy数据，对地震初学者有很大的用处。(Can use c# read segy data, are of great use for the beginners of the earthquake.)

该程序完成了一个DPSK通信系统的仿真，用均匀随机数发生器产生01比特对，用差分编码将每2比特符号映射到4种信号点中之一个，绘制出了DPSK的误码率。( This procedure has completed a DPSK communications system s simulation, produces 01 bit right with the even random number generator, maps with the differential coding every 2 bits marks to of 4 kind of signal locations, drew up the DPSK error rate. )

对Lena图像128*128，进行QF=50和QF=40的压缩，然后解压缩，并分别计算压缩图像的PSNR，给出图像压缩后的图像(Lena image of 128* 128,QF=50 and 40 compression, then uncompress, and calculate the PSNR compressed image, after image compression)

对二维图像进行离散傅里叶变换，分别给出了直流分量移动到频谱中心前后的频谱图样。(Two-dimensional images of the discrete Fourier transform, respectively, given the spectrum to move to the DC component of the spectrum before and after the design center.)
