Spread Spectrum Pattern and PN Sequence Retrieval in Wireless Ad Hoc Network: Design Approach

TLDR: The algorithm to retrieve the PN sequence & pattern of spectrum in spread spectrum system will increase the wireless network security & solve the problem of accessing the wirelessnetwork in secured way.

Abstract: Spread spectrum signaling technique is used for security purpose in wireless network because it becomes difficult to access the wireless network by unwanted users. We are developing the algorithm to retrieve the PN sequence & pattern of spectrum in spread spectrum system. This algorithm will increase the wireless network security & solve the problem of accessing the wireless network in secured way. Because, when only sender end knows the PN sequence & pattern of spread spectrum communication system the network security will be enhanced. Spread spectrum is a means of transmission in which data sequence occupies a much more bandwidth than minimum required bandwidth necessary to send it. The spectrum spreading at transmitter & de-spreading at receiver is obtained by PN-sequence which is independent of data sequence. There are two types of the spread spectrum techniques direct sequence spread spectrum & frequency hopped spread spectrum. Direct sequence spread spectrum is technique in which data sequence directly modulates the pseudo noise sequence known to only transmitter & receiver. Frequency hopping means to transmit data in different frequency slots.
