Research on π/4QPSK Modulation Communication Transmission System and FPGA Implementation

Year: 2025

Type: article

Abstract: This paper examines the π/4QPSK modulation communication transmission system, analyzing the performance advantages and disadvantages of π/4QPSK in comparison to QPSK. It also presents a comprehensive FPGA implementation scheme for a modulation communication transmission system, integrating RS channel coding, framing, frequency conversion, and other modules. This design is based on practical research and development requirements. The Xilinx Spartan6 chip board was used for board-level verification. The π/4QPSK modulated signal was transmitted via D/A conversion and radio frequency, with the transmitted waveform was looped back for reception. After A/D processing, the correctness of the designed modulation transmission scheme was verified.
