This model simulates a three phase rectifier based on space vector pulse width modulation. Parameters can be adjusted from Model properties initial call back function.
In biomedical applications it need to be using simple circuit for convey the data information ,this design it can be used as digital modulator for low bit rate. And select or programming the appropriate scheme modulation (ASK, FSK, BPSK).
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...
MATLAB code of Beamforming using QPSK modulation
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...
This is an FSK modulation spread with a PN sequence generator.
It is a simulation file that illustrates the effects of spread spectrum communications.
I am interested on collaboration.
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...
gmsk modulation of numerical data generated by a random source, the output of the modulator give two signals, only for demonstration, the first is gmsk signal and the other is gaussien frequency pulse shape
A WiMAX simulation where you can define the number of OFDM symbols to simulate, type of channel (SUI 1-6 or AWGN Channel), lots of BW and four kind of cyclic prefix. You can choose 4 different modulation as you can choose on IEEE 802.16d
Discuss the case where there a multiple (two) transmit antennas and multiple (two) receive antennas resulting in the formation of a 2x2 Multiple Input Multiple Output (MIMO) channel. We will assume that the channel is a flat fading Rayleigh...
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.
Sine wave pulse width modulation inverter uses sine wave as reference and triangular wave as carrier wave.
SPWM technique for Three Phase Inverter. Analysis fundamental improvement with respect to modulation index variation is done in simulation. Analysis can be done also for switching frequency variation for shifting the dominant harmonics
The model simulates asymmetric modulation which can be observed at second scope by zooming the waveform on time axis. In this modulation technique the reference signal is sampled at positive as well as at negative peak of the carrier and held...
The demonstration of n-PSK modulation and demodulation with my own speech, with different value of n and sampling frequency and carrier, n = 2, 4, 8, 16 ,32...
By varying Modulation Index SDM and DDM can be varied and tested.
Normally used in ILS (Instrument Landing System) applications.

This funtion will compute the probability of error in Additive White Gaussian Channel (AWGN) using BPSK modulation.
Digital modulation techniques. Digital shift keying.
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...
