There are two main types of forward error correction coding scheme:
- Block coding where a group (block) of bits is processed
as a whole in order to generate a new (longer) coded block for transmission. A
complementary block decoder is used in the receiver. Block coding is described in detail
in Section 7.3.
- Convolutional coding operates on the incoming serial bit
stream generating a real-time encoded serial output stream. A complementary serial
(convolutional) decoder is used in the receiver. Convolutional coding is described in
detail in Section 7.5.
