Repetition Decoding class.
A repetition decoder class. This takes a majority vote, biased by the ap_prob
rate, and decides if the number of 1 bits > ap_prob, it is a 1; else, it is a 0.
|
static |
Build a repetition decoding FEC API object.
frame_size | Number of bits per frame. If using in the tagged stream style, this is the maximum allowable number of bits per frame. |
rep | Repetition rate; encoder rate is rep bits out for each input bit. |
ap_prob | The a priori probability that a bit is a 1 (generally, unless otherwise known, assume to be 0.5). |
|
pure virtual |
Returns the coding rate of this encoder (it will always be 1).
Implements gr::fec::generic_decoder.
|
pure virtual |
Sets the uncoded frame size to frame_size
. If frame_size
is greater than the value given to the constructor, the frame size will be capped by that initial value and this function will return false. Otherwise, it returns true.
Implements gr::fec::generic_decoder.
