Abstract—With the growing advancements in the field of technology in this modern world, digital communication systems are increasing attractively and flexible for a secure form of data communication. Spread Spectrum overcomes the severe levels of interference that are encountered in the transmission of the digital information and rely upon shift register codes. Spread spectrum technology has blossomed from a military technology into one of the fundamental building blocks in current and next-generation wireless systems. From cellular to cordless to wireless local area network (WLAN) systems, spectrum is a vital component in the system design process. It has found important commercial applications in CDMA cellular networks as well as wireless personal communication networks. This paper mainly focuses the design of spread spectrum techniques, namely Direct Sequence Spread Spectrum (DSSS) and Frequency Hopped Spread Spectrum (FHSS) which involve for spreading the bandwidth of the signal to minimize the troubles that can arise from the vulnerabilities of conventional circuits through the channel.
