Abstract
Aiming at the application of QAM technique in the field of cable television,this paper presents a scheme of all-digital 64QAM modulation and demodulation based on FPGA.It gives the description of each module designed in VHDL,shows its timing simulation result and describes the timing problem involved in this system.Finally all-digital 64QAM modulation and demodulation is correctly realized.
