A movement of charge carriers due to the concentration gradient in a semiconductor is called process of diffusion. When charge carriers move, the current is constituted in a bar. This current due to diffusion is called diffusion curren

This program is a new way to estimate the coherence function. It s based on the MVDR and is much more reliable than the classical Welch s method implemented in MATLAB. There are 2 programs: the main program called coherence_MVDR.m and and an example, called illustrate.m, that calls the main function to show how it works. There also included 2 papers that we published on this algorithm. (This program is a new way to estimate the coherence function.
