   Low-density parity-check (LDPC) codes are a class of highly efficient linear block codes made from many single parity check (SPC) codes. They can provide performance very close to the channel capacity (the theoretical maximum) using an iterated soft-decision decoding approach, at linear time complexity in terms of their block length.

   What is the code rate of a forward error correction?

   • The Code Rate of a forward error correction expresses the proportion of bits in a data stream that actually carry useful information. There are 4 code rates used in LoRaWAN: For example, if the code rate is 5/7, for every 5 bits of useful information, the coder generates a total of 7 bits of data, of which 2 bits are redundant.

   What is forward error correction?

   • Forward Error Correction is a process of adding redundant bits to the data to be transmitted. During the transmission, data may get corrupted by interference (changes from 0 to 1 / 1 to 0). These error correction bits are used at the receivers for restoring corrupted bits.

   What is forward error correction (FEC)?

   • In computing, telecommunication, information theory, and coding theory, forward error correction ( FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels .

   What is pre-forward error correction (pre-FEC) bit error rate (BER)?

   • Optical transport network (OTN) interfaces use pre-forward error correction (pre-FEC) bit error rate (BER) for monitoring the condition of an OTN link. Use this topic to understand more about how OTN links are monitored and the supported FEC modes on devices.

   For high-speed transmission based on 16-QAM, multiple high-performance FEC codes have been studied. Table 8.1 shows some of the FEC codes and their performances. The first code is the concentrated FEC (CFEC) code adopted by the Optical Internetworking Forum (OIF) for 400ZR [95,96].
