Abstract
An approach is provided for interleaving low density parity check (LDPC) encoded bits in 32APSK modulation systems. By assigning the bits determining modulation symbols based on different bit degrees, one can efficiently find the desirable tradeoff between error performance and error floor provided by the LDPC codes in use.
