Introduction to spread spectrum - Direct sequence spread spectrum - Spreading sequences and Waveforms: - Pseudo-random sequence generation- Maximal sequences - Auto correlations and Power spectrums of codes - Characteristic polynomials - Generation of gold codes – Interference rejection for DS/SS. Frequency hopping spread spectrum - Frequency synthesizers - Multitone jamming - Hybrid systems.
Synchronization issues for spread-spectrum - Phase lock loop - Delay lock loop - Acquisition of spreading sequences – Serial search acquisition - Introduction to code tracking.
Detection of spread spectrum signals - Performance of direct sequence spread spectrum - Performance of frequency hopped spread spectrum - Performance of spread spectrum system with forward error correction. Low probability of detection - Code division multiple access (CDMA).
