摘要:
A low density parity check (LDPC) code is used within a wireless apparatus to perform forward error correction (FEC) coding. Encoding comprises the multiplication (42) with a transpose of a porti9on (44) of a parity check matrix followed by differential encoding (46). In at least embodiment of the invention, a (2000, 1600) bit-length LDPC code is used.
