Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set... Platforms: Matlab

This function convolves two very large vectors very quickly. Enormous gains in speed are due to the use of two fft's and an ifft. To find out how to use this program, put it in you 'work' folder and type "help fconv". Platforms: Matlab

This Demo gives the user sufficient freedom to vary the values of modulating and carrier signal amplitude and frequency.Accordingly it displays the time domain waveforms of both the signals. i.e. modulating and carrier signal.It also provides means of evaluating AM Envelope and the corresponding...

Many image processing applications require an extensive usage of FFT2 routine (or, in the most general case, a N-dimensional FFT) of matrices having the same dimensions. In these cases MATLAB FFT2 can result extremely inefficient. In general the execution time can be significantly reduced by... Platforms: Matlab

This script calculates BER for a numebr of SNR values in gaussian environment for QAM 16 Modulation.It calculates 100 errors for each BER measuremnet for better results.I hope this will be helpful for students of signal processing and communications alike. Platforms: Matlab
