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.

ADSL时域均衡器,包括Matlab程序和TI C62x DSP处理器上运行的C程序-ADSL Time-Domain Equalizer running on a Texas Instruments C62x digitial signal processor

此程序是一个直接序列扩频与跳频混合的扩频通信系统的仿真，扩频码用的是线性移位寄存器产生的m序列，跳频的跳点数为4。

A simple example to verify the feasibility of applying compressed sensing for channel estimation. The pilot applies a PN pattern in the frequency domain. The density of pilot is less than the Nyquist sampling rate. Also it is assumed there are sparsity in the channel taps, which is the basis for applying compressed sensing.
