ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING (OFDM) SYSTEM RECEIVER USING LOW-DENSITY PARITY-CHECK (LDPC) CODES

摘要

Arrangements relating to an Orthogonal Frequency Division Multiplexing (OFDM) receiver (200) can include performing at least one Low-Density Parity Check (LDPC) decoding attempt on a received signal (725) and evaluating at least one parity check for each LDPC decoding attempt (735). Failed LDPC decoding attempts can be counted according to the evaluated parity checks (740). The signal can be selectively processed through at least one joint demodulation-decoding loop according to the counting of failed LDPC decoding attempts (745).
