title = "Design and Implementation of a DSSS/UQPSK Demodulation Algorithm Based on FPGA",
abstract = "This paper presents a scheme of UQPSK demodulation algorithm on FPGA which is based on direct sequence spread spectrum (DSSS) communication system. The research is focused on synchronization technology of DSSS/UQPSK signal and design of synchronization loops. The main content of this demodulation algorithm includes carrier synchronization loop and DSSS code synchronization loop. Among them, carrier synchronization loop adopts a second-order feedback closed-loop based on the theory of Costas, and DSSS code synchronization loop uses a method of spread spectrum signal acquisition sliding correlation. In the project that the author participated in, the function of DSSS/UQPSK demodulation algorithm was realized successfully on the FPGA platform.",
