The Simulation and Hardware Realization of π/4 QPSK Modulator

WAN Huilin,GONG Xiaohui,YIN Kuixi,YUAN Yun(Nanjing Normal University,Nanjing 210097,China)  
A simulated comparison is made between π/4 QPSK and QPSK.The computer simulations demonstrate that π/4 QPSK has higher frequency spectrum efficiency.In addition,hardware realization was carried out and compared with software simulation.Simulations proved the validity and feasibility of this design,which can be used in mobile communication experiment and programmed control of switching equipment.
