Primary Options
Constraint length (K)
Constraint length is equal to the number of input data values (present and past) used to generate the convolutional
code in the encoder.
Code Rate (k/n)
This is the symbol output rate of the encoder, defined as the number of output bits per input bit in the encoder. For
non-punctured decoder, this can be set from 1/2 to 1/7. For punctured decoder, this can be set to m/m+1, where m
can range from 2 to 12.
Operation Mode
The operation mode of the decoder is either continuous or block.
Block Options
Termination Mode
This is the termination mode used for the convolutional coding of the input block. This parameter is required for
block operation modes.
Number of Tracebacks
Number of tracebacks performed for decoding. This option is available only when zero-flushing termination mode is
used.
