Listing of Communication in Scripts

Data stored column-wise in an input matrix are normalized as time series, with options to output just the normalized data, or the norm of each column as well. Fast, uses no loops..

  • Platform: Matlab, Scripts

Have you ever wanted to acquire, manipulate and process your audio signal with Matlab? Well, now you can. This is an experimental program built for a thesis (Bachelor Degree), that use all the Matlab functionality for "torture" an audio signal in Microsoft Wave PCM or MP3 format.

Fast Algorithm estimating the number of sinusoids in a white Gaussian noise. This algorithm use a sub-space method based on chi-square statistics of eigen values of the Autocorrelation Matrix. Example : clear, close all hidden N = 512; L_vrai = 4; fe = 2000; F = (0:(fe/2)/(N/2-1):(fe/2)); snr = [-10 -10 -10 -10]; f = [25 230 500 780]; n = 32; prob = 0.

The Matlab code investigates the harmful effects of high power amplifier on ofdm signals. It is imagined that the amplifier destroy the amplitude of the transmitted signal due to saturation and has no effect on the signal phase. The model is acceptable for solid state amplifier to some extend.

  • Platform: Matlab, Scripts

The comb pilot aided channel estimation in ofdm modulation is considered. The power of pilot subchannels is under the control. The data experience frequency selective channel then the AWGN noise is added to make the situation worse. The bit error rate is ploted versus SNR.

This code basically computes the BER of an OFDM system. The ifft size is 64 .16-QAM is the modulation Technique and convolution encoding rate 1/2 is used as the coding scheme..

  • Platform: Matlab, Scripts

The program distributes an amount power among ofdm subchannel to make the capacity of a channel..

  • Platform: Matlab, Scripts

OFDM Signal generation and decoding using 64-QAM as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. Just run the Model and with different SNRs in the AWGN Channel Block observe the performance of the OFDM.

  • Platform: Matlab, Scripts

OFDM Signal generation and decoding using QPSK as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. QAM4 and QPSK is same modulation technique. Just run the Model and with different SNRs in the Channel Block observe the performance of the OFDM.

One of the file is a guide to see where the other file should be. The other file return a 60x15 matrix (60 subchannels x 15 OFDMA Symbols) and it is said on that matrix which user has to transmit in each slot. Then we'll have to allocate the information to send it.

This function searches the interior of a signal in an attempt to find a segment that may be used in order to make the signal quasi-periodic. This can be used to reduce the influence of end effects on analyses such as the Hilbert Transform, the Wavelet Transform, the Hilbert-Huang Transform and EMD, or Hilbert Vibration Decomposition.
