CONVOLUTIONAL CODE WITH SPECIFIED END BIT COMBINATION, DIRECT LINK AND OPTIMUM SPECTRUM OF DISTANCES Russian patent published in 2012 - IPC H03M13/23 

FIELD: physics.

SUBSTANCE: method of forming a set of generator polynomials for use as a convolutional code with a specified end bit combination in order to handle data transmitted over a channel involves: (1) selecting real combinations of generator polynomials for inclusion into a pool of potentially possible codes, each real combination being a potentially possible code; (2) determining first lines of a weight spectrum for each potentially possible code in the pool and including potentially possible codes of the pool having the best first lines into a set of candidates; (3) determining the best codes from the set of candidates based on the number of first L lines in the weight spectrum; (4) selecting the optimum code(s) from the best codes; and (5) configuring the shift register circuit(s) of the data transmitter in order to realise the optimum code(s).

EFFECT: optimisation of generator polynomials of a convolutional code with specified end bit combination.
