摘要： An orthogonal frequency division multiplexing (OFDM) system with a multicell or multisector structure includes a plurality of base stations and mobile stations. Each of the base stations interleaves data for transmission to the mobile station, performs space-time coding (STC) on the interleaved data into a plurality of space-time code streams, selects one of the space-time code streams every predetermined code stream selection period such that different space-time code streams are transmitted to at least one cell or sector from among cells or sectors formed by the base station and other base stations, and outputs the selected space-time code stream as an OFDM symbol. Each of the mobile stations STC-decodes a space-time code stream obtained by performing Fourier transform on the OFDM symbol, deinterleaves the STC-decoded data, and channel-decodes the deinterleaved data into its original data.

摘要： A method and apparatus for decoding inner and/or outer codes in a mobile communication system. The inner and/or outer codes are decoded at low power and high speed. An inner decoder performs channel decoding and cyclic redundancy checking (CRC) on symbols received through a wireless network. An outer decoder performs outer coding on the received symbols. An erasure symbol identifier outputs information of erasure symbols in which a reception error has occurred. The reception error is determined from a result of the CRC on the received symbols. A controller counts the number of received symbols and the number of erasure symbols, and stops an operation of at least one of the inner and outer decoders when at least one of the number of received symbols and the number of erasure symbols is equal to a preset reference value.

摘要： A transmitting device including an encoder for receiving an information bit stream in a frame and outputting an information symbol, a first parity symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in an array with an integer number of rows and an integer number of columns. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size. A demultiplexer demultiplexes the radio frames received from the interleaver into streams of information, first parity symbols, and second parity symbols. A rate matcher bypasses the stream of information symbols and punctures the streams of the first and second parity symbols for rate matching.

摘要： Disclosed is an apparatus for stopping iterative decoding in a turbo decoder performing iterative decoding on a received frame comprised of information bits and then outputting the iteratively decoded results. A turbo decoder sequentially outputs absolute LLR (Log Likelihood Ratio) values associated with the respective information bits of the received frame by the iterative decoding, and stops the iterative decoding in response to a stop command for the iterative decoding. A minimum LLR detector selects a minimum value M(i) among the sequentially output absolute LLR values. A controller issues a command to stop the iterative decoding, if the minimum value M(i) is larger than a first threshold determined based on a minimum value Fmin among absolute LLR values output through previous iterative decoding.

摘要： 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.
