In one embodiment, the 16-quadrature amplitude modulation QAM modulator includes a logic operation device performing a logic operation on first-fourth bits of received data to generate first and second logic outputs. A first quadrature phase shift keying QPSK modulator receives the first and second bits of received data and generates a first QPSK signal. A second QPSK modulator receives the first and second logic outputs and generates a second QPSK signal. A combiner combines the first and second QPSK signals to generate a 16-QAM signal.
