Design and construction of Direct Sequence Spread Spectrum CDMA transmitter and receiver

Spread spectrum communication techniques have been widely accepted in mobile and wireless communications. They have very beneficial and tempting features, like Antijam, security, and multiple accesses. It is the purpose of this paper to describe the features of spread spectrum systems. The emphasis will be on the direct sequence spread spectrum (DS-SS) scheme, pseudo noise signals (PN), modulators and demodulators, hardware implementation and illustrate some of the DS-SS system features.
