Method and apparatus for channel encoding and decoding in communication system using low-density parity-check codes / 2450442
Apparatus and method for encoding a channel in a communication system using a low-density parity-check (LDPC) code are disclosed. Parameters for developing the LDPC code are determined and a first parity-check matrix of a quasi-cyclic LDPC code is generated in accordance with said determined parameters. A second parity-check matrix is generated by deleting a predetermined portion of the parity part in the first parity-check matrix and a third party-check matrix is generated by reordering the second parity-check matrix.

Coding and decoding of ldpc packages of variable sizes / 2443053
FIELD: communications. SUBSTANCE: method for support of coding and decoding the low density parity checking (LDPC). According to the one aspect, coding and decoding of LDPC packages of variable sizes may be supported using the set of basic parity checking matrixes of different size and the sets of lifting value that are equal to the different power of number 2. Basic matrix G of parity checking sized mBxnB can be used for coding the package out of kB=nB-mB information bits to get code word out of nB bits of code. This basic matrix for parity checking can be “lifted” by lifting value L to get lifted parity checking matrix H sized L*mBxL*nB. The lifted parity checking matrix can be used for coding of the package if up to L*kB information bits to get code word of L*nB code bits. Wide range of package size can be supporting using the sets of basic parity checking matrixes and lifting values sets. EFFECT: provision for effective coding and decoding of LDPC packages of variable sizes. 15 cl, 15 dwg
