遥测技术中QAM调制解调器的FPGA实现

QAM is a highly efficient digital modulation techniques, digital modulation techniques compared to traditional, QAM signal amplitude and phase can carry information, can take advantage of the signal plane, thus greatly improving the effectiveness of information transmission, while high Spectral efficiency. Aiming at the application of QAM technique in the field of telemetry technology，this paper presents a scheme of all-digital modulation and demodulation for 16QAM based on FPGA,this scheme is simulated in QuartuslI and accomplished by using Verilog HDL hardware description language,the paper shows simulation result, The design of the system is realized in the chip EP2C8Q208C8 belonging to ALTERA company.
