MatLab m-file DSSS
A simple model of direct expansion range, built in Matlab M-file. The appearance of errors in it starts from -10 (-100) dB, thereby demonstrates the possibility of direct expansion systems of the spectrum. model builds charts.
In telecommunications, direct-sequence spread spectrum (DSSS) is a spread spectrum modulation technique. Spread spectrum systems are such that they transmit the message bearing signals using a bandwidth that is in excess of the bandwidth that is actually needed by the message signal. This spreading of the transmitted signal over a large bandwidth make the resulting wideband signal appear as a noise signal which allows greater resistance to intentional and unintentional interference with the transmitted signal.
