Performances Analysis of Anti-disturbance of Direct-sequence Spread-spectrum System

Spread spectrum communication is suit to coal mine communication, which has some advantages such as strong anti disturbance, easy to realize CDMA. So introducing the new technology of spread spectrum communication can promote the mine communication and achieve the demand of modernization. The paper analyzes resist ability for all kinds of disturbances in spread spectrum system, and calculates the processing gain for these disturbances.
