Demodulation Fft Qam

It can be used also for computing the BER (bit error ratio) for different Eb/N0 in an AWGN channel.MSK stands for Minimum Shift Keying. Requirements: - MATLAB 7 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

DFT plays important role in DSP and used in wide variety of applications like correlation and spectral analysis. Understanding quantization errors in its computation is an important aspect of its design either for s/w or h/w implementation.A complex DFT of N points has N complex (4N real)... 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...

In this file there are two m-files.One is function and other is program. So during running the program save both file in same folder.First open the function rect ,then and run the ber_QAM file. You will get the required result.Here simulation is performed for 10,000 symbols in the presence... Platforms: Matlab

This package consist of a number of auxiliary functions that are helpful for analysing 1D and 2D signals such as surface profiles and surfaces and images. They are all built upon the built-in MATLAB FFT routine for fast execution and they replicate (when it is existing) the result produced by... Platforms: Matlab

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself.... Platforms: Matlab
