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.

This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]]. This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.
 
As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.

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'.
