M. Katta Swamy, M.Deepthi, V.Mounika, R.N.Saranya

With the ever-growing advancements in the field of technology, Digital communication systems are becoming increasingly attractive 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. This paper is in accordance with the design of Spread Spectrum techniques, namely Direct Sequence Spread Spectrum (DSSS) and Frequency Hopped Spread Spectrum (FHSS) which involve spreading the bandwidth of the signal to minimize the troubles that can arise from the vulnerabilities of conventional circuits, through channel. This paper further elaborates about the performance analysis of the above techniques which includes Signal-to-Noise(S/N) ratio and transmitted power parameters, when the transmitted signal is corrupted by Additive White Gaussian Noise (AWGN).
