Abstract: A method and apparatus is provided for encoding and/or decoding at least one data packet using a decoding algorithm based on Belief Propagation. The data packet can be encoded, and then processed according to a permutation either before transmission at a transmitter 101 or after Soft-Demapping at a receiver 103. Decoding the received processed data packet is performed using a decoding algorithm based on the Belief Propagation algorithm and linear matrix operations. Alternatively, a method and apparatus is provided in which a data packet is encoded and transmitted to a receiver 103. The receiver 103 processes or stores a binary parity check matrix of the encoding scheme used in encoding the data packet, where the processing includes linear matrix operations, and a decoder 120 decodes the received encoded data packet based on a Belief Propagation algorithm and the processed binary parity check matrix.

Abstract: The present invention relates to an apparatus and method for detecting a data rate in a turbo decoder for a mobile communication system. When a rate selector selects one data rate among a plurality of data rates, a turbo decoder repeatedly decodes an input data frame within a predetermined repetition limit number using the selected data rate and outputs the decoded data. A CRC detector performs CRC check on the decoded data and outputs the CRC check result, and a decoding state measurer measures decoding quality depending on the decoded data and outputs decoding state information. A controller then sets the repetition limit number to a predetermined minimum value, controls the repetition limit number according to the decoding state information, controls the rate selector and determines a data rate of the input data depending on the CRC check result.

Abstract: A receiving device performs reception in a service period of a broadcast signal and switches to a power saving mode in a non-service period. The service period is composed of a first period during which an application data table of an MPE-FEC frame is transmitted and a second period, following the first period, during which an RS data table of the MPE-FEC frame is transmitted. An error correction unit 12 performs one of error correction that uses the whole RS data table according to MPE-FEC, and erasure correction that uses a same number of parity bytes as bytes having bit errors. When the bit errors are corrected by the error correction unit 12 performing erasure correction, a power control unit 30 switches a receiving circuit to a power saving mode before the second period ends.

Abstract: The application relates to channel state feedback reporting in wireless communication networks and in particular to modifications of the procedure for reporting CSI as specified by section 7.2 of 3GPP TS 36.213 V10.3.0. and the corresponding RRC protocol as specified by 3GPP TS 36.331 V10.2.0. The current cycle for CSI measurement and reporting is such that the UE performs separate CSI measurements for each report. However, the coverage area of CSI measurement reporting is lower than other uplink reporting such as e.g. ACK/NACK on PUCCH which supports subframe repetition, leading to an imbalance. Therefore, it is rather clear that it is highly beneficial to support coverage extension for CSI reports. The issue then arises as to how to realize the CSI coverage enhancement on top of existing/evolving CSI reporting framework. The application proposes to realize said CSI coverage enhancement by reporting (450) the same CSI report multiple times from the UE (110) to an eNB (220).

Abstract: A transmitter (1) for use in digital radio communications systems includes: a bit corrector (14) controls bit arrangement in such a manner that a code having high significance, out of multiple codes obtained by coding, is allocated with high priority to a bit having a tendency that the likelihood enlarges at the time of symbol decision on a receiver (2) ; a multi-level modulator (15) allocates the code to the multiple bits in accordance with a predetermined symbol arrangement; and a symbol arrangement controller (18) controls the symbol arrangement from equal distance arrangement to another arrangement in accordance with a ratio of the codes different in significance. To control symbol arrangement increases the effect of bit correction and improves an error rate on the receiver (2) .
