Verification of Spread Spectrum Correlator
Lecture Notes in Engineering and Computer Science
Since the early 1940s, military communication systems, regular networking, and wireless communication systems use spreading techniques. One such technology is Spread Spectrum, where the waveform is modulated by spreading the bandwidth using a pseudorandom noise, thereby encrypting the signal. The project verifies a spread spectrum correlator and checks for its verification properties. It aims to check the correlators through 14 different designs under tests (DUTs) while correlating to the gold code (PRN), frequency, and phase. It further aims to check the correlation properties with frequency errors and phase errors. This project will allow upgrading systems with spread spectrum techniques to send and receive information with finer encryption. The project aims to provide full functional verification of the design and check if the design meets the specification requirements. The results of the project show plot of correlation characteristics with frequency and phase errors.
