Patent ID: 7581162

Claim:
A method for correcting errors in a signal transmission using a rate ¾ low density parity check (LDPC) code, comprising: encoding at least a portion of a received data message using a parity check matrix of the LDPC code; transmitting at least a portion of the encoded data message in a signal transmission over a communication channel; and receiving the signal transmission and decoding the encoded portion of the data message using a parity check matrix of the LDPC code; and wherein the encoding and decoding are performed using a parity check matrix corresponding to a coded block size (N) equal to 1944, a representation of the parity check matrix comprising: 48 29 28 39 9 61 - - - 63 45 80 - - - 37 32 22 1 0 -- -- 4 49 42 48 11 30 - - - 49 17 41 37 15 - 54 - - - 0 0 - - - 35 76 78 51 37 35 21 - 17 64 - - - 59 7 - - 32 - - 0 0 - - 9 65 44 9 54 56 73 34 42 - - - 35 - - - 46 39 0 - - 0 0 - 3 62 7 80 68 26 - 80 55 - 36 - 26 - 9 - 72 - - -- - 0 0 26 75 33 21 69 59 3 38 - - - 35 - 62 36 26 - - 1 -- - - 0.
