Claim 56:
57. A method of receiving data in a communication system, comprising:
receiving signals at a receiver via a communication channel having a channel signal-to-noise ratio (SNR);
transforming the received signals into received bits using the receiver; and
providing the received bits from the receiver to a sink device;
wherein the received signals are transformed into received bits using a decoding process that considers each bit-level separately and based upon an unequally spaced Quadrature Amplitude Modulated 64 point (QAM-64) symbol constellation and a code having a code rate; and
wherein use of the unequally spaced QAM-64 symbol constellation in combination with the code provides a gain of at least 0.2 dB compared to use of a uniformly spaced QAM-64 symbol constellation in combination with the code.
