Claim 28:
29. A method of receiving data, comprising:
receiving a signal at a receiver via a communication channel having a channel signal-to-noise ratio (SNR);
demodulating the received signal into a demodulated signal using the receiver;
determining likelihoods using the receiver based upon the demodulated signal and a symbol constellation that includes constellation points at a plurality of unique point locations, where:
the plurality of unique point locations are unequally spaced;
the constellation points each have a location and a different label; and
the locations of at least two of the constellation points are the same; and

providing a sequence of received bits from the receiver based upon the determined likelihoods and a low density parity check (LDPC) code having an associated LDPC code rate.
