Implementation 16 QAM Base Band Communication System

Implementation 16 QAM Base Band Communication System. What is QAM. In QAM two DSB signals are transmitted using the carrier of the same frequency but in Phase Quadrature to each other. Quadrature Modulator. Mathematically ? QAM(t) = m(t) cos?t + m(t) sin?t. Demodulator.
