摘要： An apparatus and method for interleaving systematic bits and parity bits to generate an output sequence that can be transmitted in multi-slot packets from a base station to a remote station in a wireless communication system. The apparatus comprises a memory element and a control element coupled to the memory element, wherein the control element is configured to demultiplex the systematic bits and parity bits into sequences, wherein the systematic bits and parity bits are sequentially distributed among the sequences. The control element is further configured to reorder the sequences and to form matrices from the reordered sequences based on an index set. Further, the control element is configured to permute the matrices forming a juxtaposed matrix having segments, columns, and elements and to interleave the columns. The control element is also configured to modulate the elements in the segments of the juxtaposed matrix and to truncate the modulated elements in the segments of the juxtaposed matrix, so as to produce the output sequence which comprises truncated modulating elements from the segments of the juxtaposed matrix.

摘要： Communication systems, including, for example, cell-based mobile communication systems, multiple satellite communication systems, or multibeam satellite systems, require reliable handoff methods between cell-to-cell, beam-to-beam, or satellite-to-satellite respectively. Recent measurement of a CDMA cellular system indicates that the system is in handoff about 30 % to 50 % of an average call period. Therefore, system reliability during handoff is one of the major system performance parameters and eventually becomes a factor in the overall system capacity. The present invention advantageously relates to novel and improved techniques for handoff in cellular communications, multibeam and multisatellite systems. The present invention combines the soft handoff mechanism with a code diversity combining technique (i.e., combining signals from multiple sources), a packet combining technique (i.e., combining multiple signals), and an iterative decoding algorithm (e.g., Turbo Coding (502)).

摘要： The invention relates to a method for data transmission on transmission channels in a digital transmission system, wherein turbo-coding for channel coding is carried out in a turbo-coder on the sender side and turbo decoding is performed with soft decision output signals on the receiver side. Service quality is determined on the basis of variances in the soft decision output signals in the turbo-decoder with the purpose of attaining improved service quality. The coding rate is adjusted by adapting dotting in such a way that a predetermined service quality is achieved. Alternatively, the number of decoding iterations is adjusted depending on the service quality. When a MAP symbol evaluator is used in the receiver side, the variances σ2LLR of the soft decision output signals of the turbo-decoder are determined and the bit error rate is estimated on the basis of the variances σ2LLR to measure service quality.

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.

摘要： The invention relates to a method for packet transmission with an ARQ protocol on transmission channels in a digital transmission system, wherein turbo-coding for channel coding is carried out in a turbo-coder on the sender side and turbo decoding is performed with soft decision output signals on the receiver side. A backward channel is provided which is used by the receiver to request once again information concerning defective packets. An RCPTC is used as turbo-code. At least part of the information suppressed by RCPTC dotting during a previous transmission is sent when information of a defective packet is once again transmitted. This additional information is included in the already available information in the receiver side, whereupon the completed information is once again decoded. When transmission is resumed, only those bits are transmitted which are additionally available in the next lowest coding rate, since said bits are not dotted. The method is then repeated until error-free decoding of the packet takes place or the entire coded information of a packet is transmitted.
