摘要： Systems and methods for decoding block and concatenated codes are provided. These include advanced iterative decoding techniques based on belief propagation algorithms, with particular advantages when applied to codes having higher density parity check matrices. Improvements are also provided for performing channel state information estimation including the use of optimum filter lengths based on channel selectivity and adaptive decision-directed channel estimation. These improvements enhance the performance of various communication systems and consumer electronics. Particular improvements are also provided for decoding HD Radio signals, including enhanced decoding of reference subcarriers based on soft-diversity combining, joint enhanced channel state information estimation, as well as iterative soft-input soft-output and list decoding of convolutional codes and Reed-Solomon codes. These and other improvements enhance the decoding of different logical channels in HD Radio systems.

摘要： A method and apparatus for processing transmissions in a wireless communication system to detect whether a transmission unit contains transmitted data. The method comprises: receiving a plurality of samples of a transmission unit; determining an average signal-to-disturbance ratio of the plurality of samples; determining for each sample at least one bit reliability indicator, which is related to the probability that the transmitted bit is a one or a zero; generating an averaged function of the bit reliability indicators from the plurality of received samples; and applying a test to compare an average of In cosh(.), with a factor proportional to the average signal-to-disturbance ratio to determine if the transmission unit contains transmitted data.

摘要： Method and decoding device for decoding a convolutionally coded input data signal y. The input data signal is multiplied with a scaling factor Lc (8) and then demultiplexed (6). The demultiplexed input data signal LcS is then turbo decoded (5) in order to obtain decoder output likelihood ratio data Λ. The scaling factor Lc is updated (7) for a next iteration in dependence on a combination of a posteriori likelihood data based on turbo decoded output data Λ and a priori likelihood data based on the demultiplexed signal LcS.

摘要： Disclosed is a storage device which includes a nonvolatile memory device, and a memory controller that performs a read operation on the nonvolatile memory device and performs an error correction operation on data read in the read operation. In the error correction operation, the memory controller estimates an error rate of the read data, and determines whether to perform a read retry operation based on the estimated error rate.

摘要： A system, method and device for error detection/estimation in OFDM communications systems is proposed. The disclosed mechanism allows an efficient error prediction in a received packet, without having to perform full FEC decoding of the packet that could impair the overall latency of the system due to the time spent in a complete FEC decoding of the packet. In order to do that, it generates a decision variable with the aim to check whether a received packet has errors or not, after performing only partial FEC decoding of the packet, without either resorting to the use of error-detection codes.

摘要： A two-reference-point-pair determining unit 101 determines two reference point pairs by selecting two transmission symbol points with their LLR computation target bit being 0 and two transmission symbol points with their LLR computation target bit being 1. An LLR computation unit 113 assigns weights to the two LLRs calculated for the two reference point pairs, respectively, followed by adding them, and further adds to the addition result a correction term that may be zero sometimes, thus computing LLR for the two reference point pairs.
