hello,
we know QPSK can be seen as two BPSK, the carriers are cos(wt) and sin(wt),
say, Icos(wt) + Qsin(wt). The I and the Q has the same amplitude and data rate.
My question is can i transmit two different kinds of signal, their data rate and amplitude are all different. The signal is A(t)cos(wt) + B(t)sin(wt).
thanks
