2. The LDPC decoder is used for Forward Error Correction (FEC) in systems where
transmitted data is subjected to errors before the reception, e.g., communications
systems, disk drives, and so on. LDPC Codes are part of recently invented ‘Iterative
decoders’, which involve multiple iterations to improve performance. Iterative
decoder shows improved performance compared to legacy convolution codes.
LDPC codes outperform Convolution codes by 3-4 dB and are characterized by a
‘water-fall’ region in their SNR – BER curve. There is an SNR threshold after which
BER decreases very rapidly. Hence, LDPC codes have found their place in most of
the latest standards including Wi-Fi (802.11n, 802.11ac), Wi-Max (802.16e), DVB-
S2, and 3GPP-LTE Advanced.
