Abstract
Disclosed is an apparatus for receiving data in a communication system, the apparatus including: a first memory for receiving data and storing input messages (i.e. V2C messages) of respective check nodes in a low-density parity check (LDPC) matrix of the received data; a second memory for storing a summation value of all the input messages of the check nodes; and a decoder for subtracting the input messages of the respective check nodes from the summation value, and updating input messages of respective variable nodes corresponding to the check nodes.
Claims16
An apparatus for receiving data in a communication system, the apparatus comprising:
- a first memory for receiving data and storing input messages of respective check nodes in a low-density parity check (LDPC) matrix of the received data;
- a second memory for storing a first summation value of all the input messages of the check nodes;
- and
- a decoder for subtracting the input messages of the respective check nodes from the first summation value, and updating input messages of respective variable nodes corresponding to the check nodes.
A method for receiving data in a communication system, the method comprising the steps of:
- receiving data and storing input messages of respective check nodes in a low-density parity check (LDPC) matrix of the received data;
- adding up all of the input messages of the check nodes and storing a calculated first summation value;
- and
- updating input messages of variable nodes corresponding to the respective check nodes, with values obtained by subtracting the input messages of the respective check nodes from the first summation value.
