    Help me get Matlab code for QPSK modulation

    Help~ If we use QPSK modulation techniques,The input data x=”10011011”,shown in figure Let T=2,E=2,fc=10Hz ,The QPSK detector is shown in figure Question:Use matlab code simulate signal : s(t),y1(t),y2(t),x1,x2。 I need the Matlab .m files,Thank you very much…
