ATViewer is a component for Delphi/C++Builder, which allows to view files of various types. There is no edit possibility, just quick view - so it s useful to implement "View file" feature in your Delphi/C++Builder application.
The following view modes are implemented:
Text, Binary, Hex, Unicode: all files, of unlimited size. Plain file dump is shown. Used ATBinHex component: only visible part of file is loaded into memory. Modes are suitable for huge files and files of unknown type.
RTF/UTF-8: RTF and UTF-8 encoded texts. File is shown using RichEdit control.
Image: all general image formats: BMP JPG ICO GIF PNG... File is shown using ATImageBox component.
Multimedia: all file types supported by MS Windows Media Player: AVI MPEG WMV MP3... File is shown using WMP ActiveX control.
Internet: all file types supported by MS Internet Explorer: HTML XML DOC XLS... File is shown using MSIE ActiveX control.
Plugins: all files supported by Total Commander Lister plugins.
There are two files in the zip folder. bpsk_spread.m and jakesmodel.m
Steps for simulation:
1] Run jakesmodel.m first
2] Then run bpsk_spread.m .
3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented
4] The resulting performance is stored in BER_awgn.
5] Now uncomment the Rayleigh Fading code in bpsk_spread.m file.
6] Same time comment BER_awgn (line 112) and uncomment BER_ray variable.
7] Run the simulation.
To compare the perfromances of the receiver using DSSS plot the BER_awgn and BER_ray
This program prints a calendar for a year specified. The user enters a
year for the calendar and the programs automatically prints the calendar
in text format.
This book code procedure according to the chapter arrangement, the 1st
chapter of example under "1" the table of contents, the 2nd chapter of
example under "2" the table of contents, to the order analogizes.
Under corresponding table of contents including Java source code
document and by it correspondence translation class document. The
reader may use software and so on the text editor opens the Java
source code document, examines this book the detailed code. 13th
chapter the code defers to the project project laying aside. May
directly use NetBeans to open the project document to carry on the
code examination.
Tasks
