原创 Android Socket 传输文件

效果：发送端用Socket发送指定路径的文件给接收端，接收端将文件存储到指定路径。发送端的MainActivity.java创建一个按钮，在按钮监听器中设置文件路径、文件名、IP地址以及端口号，然后开启一个线程执行SendFile()方法进行Socket文件发送。在SendFile()方法中，文件名和文件数据分别用name和data两个socket进行发送。public cla

Fundamentals of Wireless Communication

The writing of this book was prompted by two main developments in wireless communications in the past decade. First is the huge surge of research activities in physical-layer wireless communication theory. While this has been a subject of study since the 60’s, recent developments in the field, such as opportunistic and multi-input multi-output (MIMO) communication techniques, have brought completely new per- spectives on how to communicate over wireless channels. Second is the rapid evolution of wireless systems, particularly cellular networks, which embody communication con- cepts of increasing sophistication. This evolution started with second-generation digital standards, particularly the IS-95 Code Division Multiple Access standard, and contin- uing onto more recent third-generation systems focusing on data applications. This book aims to present the modern wireless communication concepts in a coherent and unified manner and to illustrate the concepts in the broader context of the wireless systems on which they have been applied
