(书)现代通信系统使用MATLAB第三章(ALLIANCES is a recently proposed cooperative random access protocol for wireless networks. In this paper we modify the original model to include user location information. We also derive pair-wise error probability (PEP) under Rayleigh flat fading channel and a power-law attenuation environment. Based on the PEP analysis we propose an optimal relay selection scheme, which achieves significant throughput gains as compared to the random relay selection scheme in the original ALLIANCES.)

eng_mat.rar是matlab实例,有的matlab安装时不带，可以下载拷到matlab的example文件夹里(eng_mat.rar is the matlab example, matlab installed some without, you can download the example Kaodao matlab folder)

SEGY是指地震数据模式。SEG-Y格式是由SEG 提出的标准磁带数据格式之一，它是石油勘探行业地震数据的最为普遍的格式之一。本文介绍了SEGY格式与SU格式之间的转化，SEGY格式数据的处理，及相关函数(SEGY is a seismic data format.This paper introduces the transfer between SEGY and SU, the processing of SEGY data and some related functions. )
