this file is about communication engineering Digital Transmission System this is a .m file to simulate a signal and noise ratio which the signal is NRZ bipolar signal and the noise is gaussian noise it will plot the error probability

CDMA CODE DEVOTION MULTIPLE ACCESS TECHNIQUE MATLAB CODE THAT USED IN COMMUNICATION PROGRAMING IT INVOLVE MANY MODELS YOU CAN MODULATE THE CODE AND CHOSE ANY ONE YOU NEED

warning output functions.

The function takes at least three input arguments (function, its derivative, and an initial guess). After iterations, it gives the root of the function. The fourth input argument is to change the stopping criteria.

This is the rational fractional polynomial technique for extracting modal properties of a structure
