摘要： An apparatus and method for recovering a carrier frequency of a received signal using a predefined symbol in an OFDM system is provided. A maximum value detector detects at least three values and their corresponding offsets in descending order among auto-correlation values calculated within a specific frequency offset range between a received signal and a predefined symbol. A frequency offset corrector compares a ratio of a first auto-correlation value to a second auto-correlation value with a predetermined first threshold, determines whether first and second frequency offsets corresponding to the first and second auto-correlation values are adjacent to each other if the ratio of the auto-correlation values is less than the first threshold, and determines an initial carrier frequency offset using a difference between the first frequency offset and a frequency offset correction value determined according to system, if the first and second frequency offsets are adjacent to each other and a ratio of the second auto-correlation value and a third auto-correlation value is greater than a predetermined second threshold.

摘要： An apparatus and method for reading written symbols by deinterleaving to decode a written encoder packet in a receiver for a mobile communication system supporting turbo coding and interleaving, such that a turbo-coded/interleaved encoder packet has a bit shift value m, an up-limit value J and a remainder R, and a stream of symbols of the encoder packet is written in order of column to row. The apparatus and method perform the operations of generating an interim address by bit reversal order (BRO) assuming that the remainder R is 0 for the received symbols; calculating an address compensation factor for compensating the interim address in consideration of a column formed with the remainder; and generating a read address by adding the interim address and the address compensation factor for a decoding-required symbol, and reading a symbol written in the generated read address.

摘要： A forward packet data control channel (F-PDCCH) receiver for reducing alarms relating to errors in a packet data control channel for transmitting a control signal in a mobile communication system and a method of using the same. In the F-PDCCH receiver, a decoding part decodes received symbols and calculates an information word and an absolute value of a difference between two path metrics. A false alarm reduction function compares the absolute value received from the decoding part with a predetermined threshold, and outputs a decoding value indicating whether an alarm is generated according to the comparison result. A blind slot format detector detects a blind slot format based on the absolute value received from the decoding part.

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.

摘要： A device and method for rate matching channel-encoded symbols in a data communication system. The rate matching device and method can be applied to a data communication system which uses one or both of a non-systematic code (such as a convolutional code or a linear block code) and a systematic code (such as a turbo code). In one aspect, the rate matching device includes a plurality of rate matching blocks, the number of the rate matching blocks being equal to a reciprocal of a coding rate of a channel encoder. The rate matching device can rate match the symbols encoded with a non-systematic code or the symbols encoded with a systematic code, by changing initial parameters including the number of input symbols, the number of output symbols, and the puncturing or repetition pattern determining parameters.

摘要： A method and apparatus for deshuffling received shuffled data in a communication system supporting multi-level modulation. A transmitter encodes information bits and shuffles code symbols so that systematic symbols having a relatively high priority are disposed at high-transmission reliability positions and parity symbols having a relatively low priority are disposed at low-transmission reliability positions in a modulation symbol. A receiver demodulates received data and outputs a modulation symbol having a plurality of code symbols, stores the code symbols separately as systematic symbols and parity symbols in corresponding memory areas according to a deshuffling order corresponding to the shuffling, reads the stored code symbols, decodes the stored code symbols at a predetermined code rate, and thus outputs an packet.

摘要： A method and apparatus for mapping a stream of bits output from an encoder to a stream of bits for 2m-ary modulation. The method and apparatus divides the stream of bits from the encoder into a first period and a second period. The first period includes bits with higher priority in the stream of the bits output from the encoder, and the second period includes bits with lower priority. The method and apparatus maps the bits existing in the first period to bit positions with higher reliability in a stream of m bits representing each of the bits for 2m-ary modulation, and maps the bits existing in the second period to bit positions with lower reliability in the stream of m bits.
