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...

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...

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...

The Principles of Ambiophonics*: 1.) Ambiophonics uses RACE* (Recursive Ambiophonic Crosstalk Elimination) to enable binaural listening 2.) The Speakers are positioned with a separation angle smaller than 20?*A* (called Ambiodipol) instead of 60?*A* used in stereo. No worries, in contrast to...
