摘要： Disclosed is a density evolution algorithm based on a refined definition of node and edge densities for different parts of the code. In particular, density functions ƒV(1)(i) and ƒV(2)(i) of the output edges of the variable nodes with degree i within different codeword regions w1 and we, respectively, are defined and then calculated. Further, density functions ƒC(1)(j) and ƒC(2)(j) of the output edges for check nodes with degree j within codeword regions w1 and we, respectively, are defined and then calculated. Mixture density functions of output check edges connecting variable nodes in the first codeword region and the second codeword region are then calculated to determine an LDPC code design.

摘要： A method and system for decoding a combination of a first message and a second message that were encoded using a generating matrix of a systematic linear block code is described. The combination of the first message and the second message may be decoded using a parity check matrix. If the second message is known, the first message is decoding using a first component code parity check matrix. If first message is known, the second message is decoded using a second component code parity check matrix. The parity check matrix can be derived from the generating matrix and the first message or the second message can be decoded using the first or second component code parity check matrix.

摘要： Message-wise unequal error protection is provided using codeword flipping to separate special and ordinary codewords without discarding any codewords. Special messages are encoded to ensure the codeword weight is less than a certain threshold weight. Ordinary messages are encoded to ensure the codeword weight is greater than the threshold weight. The bits of the codeword are flipped to enforce the weight criterion. Ordinary and special messages are encoded using different encodings to provide different levels of error protection. Upon receipt, codewords are separated into special and ordinary codewords for appropriate decoding. If a codeword is of indeterminate type, it is iteratively processed as both a special codeword and an ordinary codeword. The decoding result of each process is periodically checked to determine which decoding result satisfies decoding criteria.
