Spread Spectrum

Catalog description

Review of digital communication; comparison of digital modulation tech-niques such as PSK, DPSK, QPSK, MSK, and combined phase-amplitude data systems; autocorrelation and spectral characteris-tics of a spread spectrum signal. Response of a direct sequence spread spectrum signal to unwanted signals and to random noise. Pseudoran-dom codes, Gold codes, characteristics of codes used for spread spec-trum; frequency-hopping. The phase locked loop; bit synchronization, Costas receiver; tracking using the Delay locked loop and the Taudither loop; acquisition techniques; applications of spread spectrum to TDMA, navigation, RPV; state-of-the-art in spread spectrum hardware.
