Asynchronous Channel with Direct Spread Spectrum. Aspects of Correlator Implementation

Abstract

The report discusses the method of asynchronous reception of the Direct Sequence Spread Spectrum Binary Phase-Shift Keyring signal, provides structural diagrams of the receiver and transmitter. The main attention is paid to the mathematical and implementation (Field-Programmable Gate Array Xilinx) optimization of the structure used in the correlator receiver. The main advantage of the proposed correlator is the lack of a stage for selecting the initial phase of the correlated sequence, which allows you to transmit sequences with an irregular interval.
