Koala Brothers Disney Channel

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.

About Live Channel The only complete software solution for producing, streaming and broadcasting live video over the web and out to video simultaneously, replacing the functionality of expensive video production and broadcasting hardware. Whats New in this Version - Panther compatibility -...

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.

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...

In this model we have shown how adaptive filter can perform and correct up the channel effect on signal. This model is showing how filter is adapting itself to channel at each iteration. You can see different scopes displayed on model screen like adaptive filter weights, scatter plots for message...

Dent Rayleigh model is similar to Jakes but uses Hadamard function in MATLAB to make the oscillators (somewhat) independent and thus provide results that are a little more realistic than the Jakes model.For more details, please read IEEE paper by Wu Z. from 2004 (Electronics Letters, Volume: 40,...
