Abstract：Quadrature amplitude modulation (QAM) is a channel modulation techniques with relatively high efficiency of usage power and bandwidth, It is widely used in digital television, broadband and wireless transmission fields. This article in view of the 16 QAM system demodulation system,Then, Use of MATLAB tools to complete the whole system simulation,And through the constellation chart simulation analysis of the ber(bit error rate). Simulation results indicate that this system is both simple and feasible, It has a certain theoretical and practical significance that does the research about products related to QAM.
