Channel Chooser

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication. Platforms: Matlab

The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the processes used in their MATLAB scripts.The discrete input is... Platforms: Matlab

I'm actually having trouble with the equalization of the channel, because the doppler effect introduces phase rotation, which I don't know how to correct. If anyone could help me, I' d be really thankful. Platforms: Matlab

Here is a simulation based proof highlighting the superiority of the MMSE[Min Mean Sq Error] channel estimator over the LS[Least Sq] estimator.The two parameters of evaluation turn out to be, quite logically, the SER[Symbol Error Rate] and the Mean Square Error.The channel is assumed to be... Platforms: Matlab

In this programe a highly scattered enviroment is considered. The Capacity of a MIMO channel with nt transmit antenna and nr recieve antenna is analyzed. The power in parallel channel (after SVD decomposition) is distributed as water-filling algorithmThe pdf of the matrix "lanada" ( V in SVD... Platforms: Matlab

The Additive Noise Channel and the Additive Guassian Noise Channel are the simplest of all signal channels.The script mimics any experiments on these channels. Platforms: Matlab

Groovy, Funky Channel 27! The only CMS with a hologram developer!Channel 27 is a hierarchical page-centric CMS, with support for multiple users and user levels. A simple and very modular design means it is easy to extend and maintain. Platforms: PHP

AMP Sidebar Chooser allows users to associate sidebars to posts, pages, or any custom post type through the WordPress post editor. Install : 1. Upload the 'amp_sidebar_chooser' folder to your /wp-content/plugins/ directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3.... Platforms: PHP

Identity Chooser helps you to always use the correct identity when composing a new email. Platforms: *nix

The Hi-Tech Channel sidebar gadget was developed to be a small tool that will enable you to receive and read Hi-Tech news from your desktop. Platforms: Windows

Replacement for the SCCP channel driver in Asterisk. Extended features include Shared Lines, Presence / BLF, customizable Feature Buttons, and Custom Device State. Visit our discussion mailing list for help and join us as a developer if you like. Platforms: Mac, BSD, Linux

Java package providing a simple and configurable key binding chooser dialog. This includes an editor for making and editing lists of bindings in a variety of persistence formats. Platforms: Windows, Mac, Linux

A tool to transform single channel C code into multichannel C code. We are using pyparsing to provide a C sensitive find/replace mechanism. The resulting code is more testable than hand edited. The initial source base is DSP code. Platforms: Windows, Mac, Linux

App Language Chooser lets you run an application using the language of your choice, to display the user interface. It is useful as a developer tool for localizers, or when you do not want a specific application to use your preferred system language. Platforms: Mac

Groovy, Funky Channel 27! The only CMS with a hologram developer! Channel 27 is a hierarchical page-centric CMS, with support for multiple users and user levels. A simple and very modular design means it is easy to extend and maintain. Platforms: Windows, Mac, *nix, PHP, BSD Solaris

The user can immediately locate what he has been searching for in the long options list just by typing.With each character the user types in the text field, the available items listed are narrowed down (similar to a help file's inailable ire). Platforms: JavaScript

If you'd like to know where visitors to your site live, add this to your feedback forms. They just choose a region, and the second menu changes appropriately, allowing them to choose their country. (If they choose USA, it allows them to select their state). Platforms: JavaScript

The MATLAB program simulates binary frequency shift keying (BFSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random... Platforms: Matlab

Randomly generated information is modulated using 16 QAM and passed through Rayleigh fading channel and AWGN is added.PSAM (pilot symbol assisted modulation)i.e pilot symbols are inserted into sequence of information symbols periodically is done before transmission inorder to estimate channel...
