PPP Deflate压缩协议（PPP Deflate Protocol） 摘要 点到点协议（PPP）[1]提供了一种在点到点链路上传输多协议数据报的标准方法。压缩控制协议（CCP）[2]提供了一种在PPP封装链路上协商和使用压缩协议的方法。本文档描述了如何使用PPP Deflate压缩协议压缩PPP封装报文。 -PPP Deflate compression protocol (PPP Deflate Protocol) Abstract point-to-point protocol (PPP) [1] provides a point-to-point link, the multi-protocol data transmission of standard methods. Compression Control Protocol (CCP) [2] provides a link in the PPP Packaging consultations on the agreement and the use of compression method. This document describes how to use the PPP Deflate compression compression PPP agreement Packaging paper reported.

数字调制技术一套的基础功能选择特定的调制方案。一般的基础功能是互相正交的。可以使用 "克施密特正交化" 过程派生的基础功能。一旦选择了基础功能，任何信号空间中的向量可以表示为基函数的线性组合。 在正交相移键控 （QPSK） 两个正弦波 (sin 和 cos） 作为基函数调制的。调制被通过不同相的基础功能，根据消息符号。在 QPSK，调制是基础，在那里有一个符号包含 2 位的象征。
