Spread Spectrum Systems

Course Description

Baseband spectrum spreading, spread-spectrum characteristics, interference and jamming margin. Processing gain, direct-sequence spread-spectrum systems (DSSS). Characteristics and generation of PN sequences. Detection receiving signal in spread spectrum systems. Use of spread spectrum in mobile systems (especially 3G). Orthogonal codes. Problems of initial synchronization of received codes. Mobile users separation in 3G mobile communications, uplink problems. Special codes with low cross correlation and satisfactory autocorrelation - encryption of mobile users. Rake receiver, performance and basic features. Use a frequency hopping system with public mobile systems. Multi-carrier modulation and spread spectrum systems.
