Backpropagation neural network
no vote
This MATLAB program implements a multi feedforward neural network where weights are updated pattern wise using backpropagation algorithm. It also plots the Error function vs the number of epochs to show the convergence of the algorithm. The given network is 2-2-1 network,but the number of neurons at each layer can be easily changed and also it works for any given pattern.

Effects of Chromatic
Dispersion in single and multichannel fiber-optic communication systems
The recent years have
witnessed resurgent interest in coherent optical communications. Advanced
digital modulation formats such as DPSK, DQPSK, and MSK have been demonstrated
at 40Gbps over long distances. However, various channel induced signal
impairments due to chromatic and polarization mode dispersion and nonlinearity
limit the achievable bit rate and distance. Such effects have been studied
mostly on single channel communication systems.
This work
uses MATLAB Simulink modeling to incorporate chromatic dispersion (CD) in
single channel
