摘要： A decoding algorithm with an enhanced parity check matrix and a re-encoding scheme for LDPC codes is disclosed. The decoding algorithm includes the steps of: providing the enhanced parity check matrix; receiving a message part of an original codeword encoded by a generator matrix from the enhanced parity check matrix; setting a LLR for each bit node of the enhanced parity check matrix; processing hard decision on the message part of the original codeword; encoding the message part of the original codeword by the generator matrix to generate a new codeword having a generated parity part; comparing the original parity part with the generated parity part to find out bits of difference; voting candidate error bits to choose the most probably erratic bits; modifying LLR of the chosen bits to have a modified codeword; and processing a conventional iterative decoding procedure on the modified codeword to have a processed codeword.

摘要： A wireless device generates a High Efficiency (HE) Physical layer Protocol Data Units (PPDU) including a non-High Throughput Signal (L-SIG) field and transmits the HE PPDU. Transmitting the HE PDDU includes transmitting a set of extra tones with the L-SIG field. The set of extra tones include a sequence of values, and first, second, third, and fourth values of the sequence of values respectively correspond to BPSK constellation values of −1, −1, −1, and +1. The set of extra tones may include −28th, −27th, 27th, and 28th subcarriers, relative to a center (zero) subcarrier, of a 20 MHz bandwidth of the HE PPDU, and may be used to transmit the first, second, third, and fourth values of the sequence of values, respectively. Another wireless device may receive the HE PPDU, and may use the set of extra tones to estimate a channel.

摘要： A method including selecting a factor based on a number of bits in a codeword and a natural number and generating a model matrix including first and second matrices having data and parity bits. Hamming weights of the model matrix are not constant and Hamming weights of columns of the model matrix follow a statistical distribution dependent upon a codification rate of a channel. A compact matrix is generated by replacing elements of the model matrix equal to: 1 with a pseudo-random positive whole number; and 0 with −1. A quasi-cyclic code is generated by replacing in the compact matrix: positive elements with identity matrices; and elements equal to −1 with null matrices. A number of rows and columns in each of the identity and null matrices is equal to the factor. The quasi-cyclic code is applied to a word to generate a codeword, which is transmitted on the channel.

摘要： An apparatus and method are provided for transmitting and receiving a quasi-cyclic Low Density Parity Check (LDPC) code in a multimedia communication system. In the method, a signal transmission apparatus generates a quasi-cyclic LDPC code, and transmits the quasi-cyclic LDPC code to a signal reception apparatus. The quasi-cyclic LDPC code is generated by encoding an information word vector using a child parity check matrix, generated by performing one of a scaling operation, a row separation operation, and a row merge operation on a parent parity check matrix. In the scaling operation, a size of the child parity check matrix is determined. In the row separation operation, each of rows included in the parent parity check matrix is separated. In the row merge operation, the rows included in the parent parity check matrix are merged.

摘要： Low-Density Parity-Check (LDPC) codes offer error correction at rates approaching the link channel capacity and reliable and efficient information transfer over bandwidth or return-channel constrained links with data-corrupting noise present. LDPC codes also offer error correction performance approaching channel capacity exponentially fast in terms of the code length, linear processing complexity, and parallelism that scales with the code length. They also offer challenges relating to the decoding complexity of the binary error-correction codes themselves and error floors limiting achievable bit-error rates. A new Relaxed Half-Stochastic (RHS) decoding algorithm is presented that reduces decoding complexity for high decoding throughput applications. The RHS algorithm uses an approach based on stochastic decoding algorithms but differs significantly from the conventional approaches of LDPC decoder implementation. The RHS algorithm also leads to a randomized decoding technique called redecoding that addresses the error floor limitation.
