| Abstract: | As Compared with other communication systems,the spread spectrum communication system is of a special virtue, that is, it can accomplish the communication task under the circumstance of negative signal-to-noise ratio.On the basis of Shannon formula,the relationship between band spread and power improvement under certain circumstance is analyzed, and with Matlab as a mathematical tool the corresponding simulation analysis also carried out. |
