Detailed Description

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.

Member Function Documentation

static generic_decoder::sptr gr::fec::code::repetition_decoder::make ( int  frame_size,
int  rep,
float  ap_prob = 0.5 
)
static

Build a repetition decoding FEC API object.

Parameters
frame_sizeNumber of bits per frame. If using in the tagged stream style, this is the maximum allowable number of bits per frame.
repRepetition rate; encoder rate is rep bits out for each input bit.
ap_probThe a priori probability that a bit is a 1 (generally, unless otherwise known, assume to be 0.5).
virtual double gr::fec::code::repetition_decoder::rate ( )
pure virtual

Returns the coding rate of this encoder (it will always be 1).

Implements gr::fec::generic_decoder.

virtual bool gr::fec::code::repetition_decoder::set_frame_size ( unsigned int  frame_size)
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.
