Abstract
A data transmission system includes a transmitter circuit. The transmitter circuit receives regular data bits and auxiliary data bits. The transmitter circuit encodes a first subset of the regular data bits to generate a first subset of encoded data comprising pairs of symbols that are used in quadrature amplitude modulation. The transmitter circuit encodes the auxiliary data bits and a second subset of the regular data bits to generate a second subset of the encoded data comprising at least one pair of symbols that are unused for encoding by the quadrature amplitude modulation. The transmitter circuit generates a modulated output signal that indicates the first and second subsets of the encoded data using pulse amplitude modulation.
