Abstract:
A low-density parity check (LDPC) encoder and input configured to receive an incoming signal stream. The encoder generates, from a block code H-matrix comprising a data portion and a parity check portion, a continuous H-matrix by concatenating the data portion into successive, recurring, data blocks that are separated by a specified symbol interval, and performs LDPC encoding of each data portion using the parity check portion associated with the data portion using its associated parity check portion. Additionally, a Trellis-based low-density parity check (LDPC) decoder configured to receive an encoded stream and decode the received signal to recover the signal stream.
