hi, i wanted to know what is the pulse shape of the modem.oqpskmod? and if it is not half-sine pulse shape, how is it possible to make it half-sine pulse shape as it is stated in ieee 802.15.4(zigbee) standard where it shows it as follows

    p(t)=sin(pi*t/2*Tc) if 0<=t<=2Tc
    p(t)=0 if otherwise

? thanks a lot!
