Direct Sequence Spread Spectrum Signal’s Demodulator Acquisition Implementation Based on Fast Fourier Transform. Part 1. Problem Statement and Solution Approach
E. Brusin · Proceedings of Telecommunication Universities · 2023
The article is dedicated to direct sequence spread spectrum signals acquisition. Communication channels that use direct sequence spread spectrum signals are characterized by significant delay and carrier frequency shift as a rule. That’s why the acquisition is most significant problem in receive equipment design. Suggested approach to acquisition problem base on the Fast Fourier Transform and discussed modeling suggested algorithm’s results.
