Abstract:

The principle of QPSK modulation is introduced.A system design of QPSK modulator based on the System Generator platform is presented.The design starts with construction of functional modules in the environment of matlab/simulink to build the system model.The design of QPSK modulator is completed after functional simulation and verification.The simulation results show that the designed modulator can generate the correct QPSK waveform,which achieves anticipated results.

Key words: System generator;QPSK;digital modulation
