spread spectrum communication systems refer to the transmission of information with a particular spectrum of spreading function expansion into broadband signal into Channel Tunnel, and then use some of its means of compression, thus acquiring the transmission of information communication systems. In the same transmission of information necessary for RF bandwidth than we have been familiar with the various requirements of the modulation bandwidth to a much wider. Spreading information bandwidth is the bandwidth of at least a few dozen to several tens of thousands of times.
