| 摘要 | Aiming at QPSK modulation digital system with variable rate, a novel implementation method based on field programmable gate array (FPGA) is proposed, which can support 4.88Kbps to 2Mbps and even higher continuous bit rate. The design adopts mixed multiplier, numerically controlled oscillator (NCO) and integral comb filter (CIC), and describes the structure of carrier recovery circuit and signal recovery circuit, which can be ported to any FPGA device. The proposed design has its hardware test in the Xilinx Virtex-5 FPGA platform. The hardware test results show that the proposed demodulator only takes up 15% available logical unit of Xilinx Virtex-5 FPGA device, revealing superior ability in efficiency. © Xiquan Xia. |
