指纹图像小波标量量化
应用背景“指纹”,在其狭义的意义上留下了一个印象,由“摩擦脊”和“一人”,“手指”,从犯罪现场的指纹恢复是一个重要的方法,法医学。指纹是容易沉积在合适的表面(如玻璃、金属或石料磨光)的自然分泌的汗水从汗腺 ; ;这是目前表皮脊。在更广泛使用的术语,指纹的痕迹,从任何部分的人或其他与动物的摩擦脊的痕迹,手。从鞋底的鞋底上印出来,也能给人留下一种摩擦脊的印象。对指纹识别的印象可能是由油墨或其他物质转移到皮肤上的一个相对平滑的表面,如指纹卡的峰,指纹记录通常包含2个手指和拇指从垫上,虽然指纹卡也通常记录下关节领域的手指。人的指纹是详细的,独特的,难以改变,并在一个人的生活,使他们适合作为人类身份的长期标志。他们可以由警方或其他有关当局用来识别个人谁希望隐瞒自己的身份,或者鉴定人丧失劳动能力或死亡,因此无法确定自己,作为一个自然灾害的后果。指纹分析,在第二十世纪初使用以来,已导致许多罪行得到解决关键技术指纹图像的WSQ(小波标量量化)优于其他有损压缩方法,如JPEG,而被FBI(美国联邦调查局)的指纹图像压缩标准。wsq是一种有损压缩的方法,非常适合保存灰度图像的高分辨率细节的同时保持高的压缩比率通常12:1 15:1。cognaxon WSQ图像库提供添加WSQ的简单方法图像格式支持您的软件项目。WSQ图像库读取和WSQ和其他31个之间的转换图形文件格式,它是小的(~ 1.5 MB)和快速,并具有图形格式转换实用程序。支持格式:BMP,TIFF读WSQ,JPG,JPEG,TIF,JPE,PNG,GIF,PSP,JFIF,RLE,DIB,TGA,赢,VST,VDA,ICB,传真,EPS,PCX,PCC,SCR,RPF,RLA,SGI,RGBA,RGB,BW,PSD,PDD,PPM,PGM,PBM,CEL,PIC,PCD,切,敌我识别,ICO,WMF,电动势。书写格式支持:FBI的WSQ -小波标量量化,BMP Windows位图图形,标注信息文件TIFF格式(没有压缩),PNG便携式网络图形,JPEG格式的联合摄影专家组,RGB硅图形国际(解压),TGA -创辉Targa图形。

OFDM_m
完整的OFDM链路程序并作了较为具体的解析从基本的bpsk,qpsk,qam到实际的ofdm系统,cdma链路,mac层仿真分析.(Orthogonal frequency division multiplexing (OFDM) is becoming the chosen
modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
countless applications. Here, at the Georgia Institute of Technology, one of such
teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part
of the Georgia Center for Advanced Telecommunications Technology (GCATT).
The purpose of this report is to provide Matlab code to simulate the basic processing
involved in the generation and reception of an OFDM signal in a physical
channel and to provide a description of each of the steps involved. For this purpose,
we shall use, as an example, one of the proposed OFDM signals of the Digital
Video Broadcasting (DVB) standard for the European terrestrial digital television
(DTV) service.)
