Matrix Based

It simulates three phase simple PWM-180 degree conduction based inverter. Frequency and output voltage can be changed using slider gains block used.

This program deals with Spread spectrum communication systems using chaos as the sequence generators.In coming days I will be updating it with complete chaos based generators Frequency Hopping and CDMA systems with multiple users and till oustic networks poustic networks phase.

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming. There are two different minimum...

CONV_MTX Convolution matrix. If 'x' is a column vector of length 'nx', then conv_mtx(x,nh) gives a toeplitz matrix 'X' of size (nx+nh-1) times (nh). 'nh' is the length of the column vector 'h' with which 'x' is convolved. Thus finally 'X*h' is same as conv(x,h). If 'x' and 'h' are row vectors,...
