| Abstract: | According to the baseband digitized theory,a multimode high speed QAM modulator is designed. The system design is given first.Then some units are designed, including encoder,mapper, shaping filter, etc.A scalable QAM modulate platform was implemented. It can generate some multimode QAM IF signals,the bit rate of which is up to 256Mbps.It can be used in the measure of high speed QAM demodulator. |
