Forward Error Correction (FEC) is a common technique used in telecommunication systems to control error in the data transmission over noisy transmission channels. The key concept is to encode the signal in a redundant way by using Error Correcting Code (ECC) in the transmitter; this allows the receiver to detect a limited number of error bits in the transmitted signal and often to correct these errors without the need of re-transmitting the signal.
Parameters
- Decoder Objects
- Object defined by an Decoder Definition block
- Threading Type
- options: [capillary, ordinary, none]
- Annihilator
- Puncture Pattern
- a puncture pattern of '11' defines 'no puncture'.
