Classification: CPC H | IPC H

Claim 0:
1. A transmitter, comprising:
an integrated circuit that takes input bits as input and provides a quadrature amplitude modulation (QAM) signal as an output for transmission, the integrated circuit comprising:
a first quadrature phase shift keying (QPSK) modulator that generates a first QPSK signal based on a first bit pattern and a second bit pattern;
a second QPSK modulator that outputs a second QPSK signal based on a third bit pattern and a fourth bit pattern, wherein an amplitude ratio between the first QPSK signal and the second QPSK signal is two;
a combiner circuit component that generates the QAM signal based on the first QPSK signal and the second QPSK signal, wherein the transmitter wirelessly transmits the QAM signal; and
a bit splitter that splits the input bits into a plurality of bit patterns comprising the first bit pattern, the second bit pattern, the third bit pattern, and the fourth bit pattern, wherein the bit splitter, the first QPSK modulator, and the second QPSK modulator are integrated components of the integrated circuit.
