Baseline Fit each column in "x". There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput. Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated from selected points and then applied to the data.

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment. It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER. I hope this will help students alot. Please feel free to contact me should anyone has any queries.

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits. QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput. I hope this will be helpful for students of wireless communication.

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 samples added to each signal sample.

This m-file finds the bit error rate performance of BPSK DS-SS system over (i) AWGN channel and (ii) Slow Rayleigh fading channel corrupted by AWGN. Compare the performance with simple BPSK system. In this simulation I have used two functions.So to see the result open all the files and then run ber_performance file.

A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of '0's and '1's is mapped into sequence of +E and E where E represents the signal energy. E may be normalized to unity The Gaussian noise generator is used to generate the sequence of '0' mean and variance dcDo2 Gaussian random numbers.

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 of additive Gaussian noise at different values of SNR.

The transmitter is the combination of three distinct parts: the preamble, the data input and the modulation circuitry. The data is transmitted in blocks of 120 bits. An eight bit preamble with pattern 10101001 is attached in front of every packet to facilitate packet synchronization at the receiver.

This script simulates the Binary Amplitude Shift keying. Since BASK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for 5 bits, so that the results are visible. This is code for BASK only, means it can only modulated two digital states.

This script simulates the Binary Frequency Shift keying. Since BFSK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for few bits, so that the results are visible. This is code for BFSK only, means it can only modulated two digital states on two frequencies.

This is my first file here on file exchange. Improvements and comments are welcome. If you simulate a digital communication system there will be always some biterrors. Doing a XOR operation will result in the different bits. But how many single bit errors, double bit errors and so on are there ? Because I couldndlDLt find such a function in the simulink library I wrote it by myself.

Let us assume the signal model: Y(k)=HX(k)+B(k) This script provides a method for the blind recognition of the number of sources (the size of X(k)). The noise must be spatially white and the number of receivers is assumed to be stricly greater than the number of sources.
