i have 2 binary streams I and Q , i want to modulate them using 16 QAM , i.e both on same carrier which is 2.4 ghz but the carriers are orthogonal , i.e sin & cos
i hope that i cleared it..

That makes no sense. If you have two independent binary serial streams, you would only need 4-QAM (or in other words QPSK).

That is, unless the two streams have independent random clock rates, in which case you could never demodulate the resulting QAM pattern.
