ABSTRACT:
A method, system, apparatus and computer program product for correcting errors in a signal transmission using a rate ¾ low density parity check (LDPC) code. At least a portion of a received data message is encoded by using a parity check matrix of the LDPC code. The encoded data message is transmitting in a signal transmission over a communication channel to a receiving device in the communication network. After being received, the encoded portion of the data message is decoded using a parity check matrix of the LDPC code to obtain the data message. For example, the encoding and decoding can be performed using a parity check matrix corresponds to a coded block size (N) equal to 1944 for communicating data in compliance with an 802.11n standard.
