Implementation of High Order QAM Modulator Based on FPGA
He Li · Modern Electronics Technique · 2008
Aming at the application of QAM modulation technique in the digital wave communication system,this paper introduces the structure scheme of MQAM system which takes 64QAM for example.The design is simulated in QuartusII and Matlab software development platform.The FPGA design of each module of 64QAM and its modulate system is carried out with the method of schematic-based design and Verilog HDL-based design.Because the 256 QAM and 64 QAM has the same rectangle constellation.So this design can adapt to 256QAM modulation through revising the Verilog HDL program.
