摘要： An error protection key generation method and system are provided, the method being used to generate a key for use in computing an error protection code for an input data value according to a chosen error protection scheme. The method comprises inputting a plurality of desired data value sizes, and then applying a key generation algorithm to generate a key for use in computing the error protection code for a maximum data value size amongst the plurality of data value sizes. The key generation algorithm is arranged so that it generates the key so as to comprise a plurality of sub-keys, where each sub-key is associated with one of the input data value sizes, and where each sub-key conforms to a key requirement of the error protection scheme. As a result, a generic key is produced containing a plurality of sub-keys, where each sub-key is associated with a particular desired data value size, and can be extracted and used independently given that each sub-key conforms to the error protection scheme requirements. This provides significant benefits in the design and verification of error protection circuits using such keys.

摘要： Data puncturing ensuring orthogonality within communication systems. Puncturing is employed within communication systems to ensure orthogonality (or substantial orthogonality) of various transmissions between communication devices within communication systems. Any of a variety of types of signals can be employed herein including uncoded signals, turbo encoded signals, turbo trellis coded modulation (TTCM) encoded signals, LDPC (Low Density Parity Check) encoded signals, and RS (Reed-Solomon) encoded signals, among just some types of signals. A first transmission can be made from a first communication device to a second communication device, and the second communication device can sometimes request a subsequent transmission (e.g., a re-transmission) from the first communication device to the second communication device. Oftentimes, different information is sent from the first communication device to the second communication device within the subsequent transmission. Herein, each of these transmissions can be ensured to be orthogonal.

摘要： An encoding apparatus derives a bit order based on a puncturing table that specifies different puncturing patterns for different transmission rates. The encoding apparatus then generates an error correcting code from an input information bit string and rearranges the error correcting code in the derived bit order. The error correcting code is punctured by taking a number of consecutive bits from the rearranged error correcting code. The number of bits taken varies depending on the transmission rate. The punctured error correcting code is output to a decoding apparatus, which realigns the code bits according to the transmission rate and the puncturing table, then uses the realigned error correcting code to correct errors in erroneous data. Rearrangement of the error correcting code makes the puncturing process more efficient by avoiding the need to decide whether to take or discard each bit individually.

摘要： A rate matching method is provided for a mobile communication system that performs an adjustment to a code rate based on an optimal level by puncturing or repetition to respective bit streams of transport channels. The rate matching method is preferably applicable to uplink and downlink rate matching for channel coding including turbo coding, convolutional coding and the like. The rate matching method for uplink can include executing coding for bits of a transport channel, and branching off the bits into a plurality of sequences, constructing a first interleaving pattern for the plurality of sequences, constructing a virtual interleaving pattern for at least one sequence based on a mapping rule with a corresponding first interleaving pattern and calculating different bit shifting values in each column of each virtual interleaving pattern. Then, a bit position to be punctured is determined in each constructed virtual interleaving pattern using the calculated bit shifting values.

摘要： Disclosed is a method of improving iterative decoding of short codes within a demodulator. The vector of metrics of the bits considered at the output of the demodulator is decoded. The value of the check code of the CRC of the decoded word is compared with a predetermined value. If the value of the CRC is considered to form an acceptable message for the decoding step, the decoded word is transmitted to the recipient. If the value of the CRC is incompatible with a correctly decoded message, then the parameters for iterative decoding of the initial message are modified that were received from the demodulator and executing at least one new iterative decoding step with these new parameters.

摘要： A method and apparatus are disclosed for forming a frame of interleaved information bits in a communication system, where the decoding of the frame of interleaved information bits may begin before all of the bits in the frame are received. An exemplary interleaved frame is formed by receiving a frame of N information bits within the communication system; encoding the information bits at a code rate R to provide encoded bits; and arranging the encoded bits into a frame of N/R coded bits, wherein a plurality of puncturing patterns pi are applied to the frame of N/R coded bits such that a code rate of R/ai is produced for each of the plurality of puncturing pattern pi. The arrangement of encoded bits involves applying a puncturing pattern pj to the encoded bits; and applying a permutation function to the punctured encoded bits to generate a fractional section of the frame of N/R coded bits. The fractional section of the frame of N/R coded bits comprises N/R*aj bits.

摘要： Provided is a method for forming a rate compatible code using high dimensional product codes and a computer-readable recording medium for recording a program that implements the program. The rate compatible code, which can provide various encoding rates, is formed by discriminating parity blocks and determining a punctured pattern for each parity block, m being more than two. The method includes the steps of: a) forming an m dimensional product code by using a systematic block code; b) dividing the m dimensional product code into an information block and 2m-1 parity blocks; c) allocating indices to the divided blocks of the information block and 2m-1 parity blocks; d) finding all combinations of the information block and the parity blocks which are adjacent to the information block; e) estimating a first weighting factor of w1 for the all combinations; f) if there are first combinations having the same weighting factor w1, estimating a second weighting factor of w2 for the first combinations having the same weighting factor w1 as second combinations; g) selecting a combination having largest weighting factor among the second combinations having the second weighting factor w2; and h) forming rate compatible codes by using the selected combinations based on the w1 and w2.
