Abstract
A method of decoding a received message includes: determining a weighting vector corresponding to at least one bit of the received message according to a syndrome and a parity check matrix; determining a bit state of the bit according to a bit value of the bit; changing the bit state according to the weighting vector and a flipping threshold, wherein a change range of the bit state is variable; and flipping the bit according to the bit state.
Claims7
A decoding apparatus of a received message, comprising:
- a weighting calculation unit, arranged for determining a weighting vector corresponding to at least one bit of the received message according to a syndrome and a parity check matrix;
- a state determination unit, arranged for determining a bit state of the bit according to a bit value of the bit;
- a flipping calculation unit, arranged for generating a bit flipping vector for changing the bit state according to the weighting vector and a flipping threshold, wherein a change range of the bit state is variable;
- and
- a flipping processing unit, arranged for changing the bit state of the bit and flipping the bit according to the bit state.
