| Abstract: | According to the ultimate principle of the MQAM modulation, the tool of System Generator in ISE DS is used to design a multimode QAM modulator based on FPGA.After the system design schematic is given, some units are specified, including scrambler, serial to parallel, differential encoding, mapping, and shaping filter, etc.Then, the 64QAM baseband modulation and IF design are realized.The QAM modulator is ultimately implemented on the FPGA device. |
