Application of direct spread spectrum sequence

• Cordless phones operating in the 900 MHz, 2.4 GHz and 5.8 GHz bands. 
• United status GPS technology, European Galileo and Russian GLONASS satellite navigation systems used DS/SS system with a single PN code in conjunction with FDMA and later it is used to achieve CDMA with multiple PN code.  
• Used in the low probability of intercept signal.
• It obtain message privacy.
• Used military and many commercial application.
• The unique spreading codes support code division multiple access.
• Support various decision making level.
• To reject unintentional  interference.
• To minimize self interference due to the multi-path propagation.
• It is used in automatic meter reading. 
• Used in IEEE 802 11b and Zigbee network. 
• Radio controlled model automotive vehicles.
