OFDM及其基带FFT实现原理以及OFDM的载波和符号同步问题-and OFDM baseband FFT principle and the carrier OFDM symbols and Synchronization

fd_set参数：一个用于检查可读性（readfds），一个用于检查可写性（writefds），另一个用于例外数据（exceptfds）。从根本上说， fd_set数据类型代表着一系列特定套接字的集合-fd_set parameters : a check for readability (readfds) one could write a check for (writefds) Another exception for the data (exceptfds). Fundamentally speaking, fd_set data types represent the range of specific set of socket

天线是由韦伯斯特的字典定义作为"通常是金属设备 （比如杆或线) 发射或接收无线电波。"IEEE 标准定义的 天线 （IEEE Std 145 – 1983） ∗ 的术语定义的天线作为"一种手段发射或接收无线电波"。换句话说，天线是过渡自由空间与引导的设备，如图 1.1 所示的结构。指导设备或线路可能采取同轴线或空心管的形式 （导），它用来运输从发射的电磁能量源到天线，或从到接收器天线。在前一种情况，我们有发射天线和后者的接收天线。

本文是一篇经典的基于离散余弦变化的信道估计论文，摘自IEEE的文章，对初学者有帮助。-This article is a classic change based on the discrete cosine channel estimation papers, taken from the IEEE article, for beginners helpful.

我们自己创建各个的头部,系统只是把它们发送出去. 在实例中,由于我们要修改我们的源IP地址, 所以我们使用了setsockopt函数,如果我们只是修改TCP数据,那么IP数据一样也可以由系统来创建的. -To create all our own head, the system only to send them out. In the example, because we have to modify our source IP address, so we use the setsockopt function, if we just amend the TCP data, then the IP can also be from the same data system to create the.
