    摘要： A cell search apparatus and method in an OFDM mobile communication system are provided. In the cell search apparatus, a symbol synchronization acquirer acquires OFDM symbol synchronization by performing CP correlation for a plurality of OFDM symbol intervals. A frame cell synchronization acquirer sorts received OFDM symbols according to the acquired OFDM symbol synchronization, and acquires frame cell synchronization by performing preamble correlation for a plurality of frame cell intervals. A pilot pattern detector sorts received frame cells according to the acquired frame cell synchronization, and detects a pilot pattern for identifying a base station by monitoring a plurality of frame cells.

    摘要： A transmitting/receiving apparatus and method in a mobile communication system are provided. In a transmitter, an encoder encodes input information data and outputs systematic bits on a first channel and redundancy bits on a second channel. A first channel interleaver interleaves the systematic bits and a second channel interleaver interleaves the redundancy bits. A modulator maps one channel data of I and Q channel data, received from the first channel interleaver and another channel data of the I and Q channel data, received from the second channel interleaver to a modulation symbol using different mapping rules for I and Q channels.

    摘要： An apparatus and method for changing a signal mapping rule in an hybrid automatic repeat request (HARQ) system are provided. In a transmitter in an automatic repeat request (ARQ) system according to the present invention, a memory stores different signal constellations for a predetermined modulation scheme according to retransmission numbers (k). A modulator reads a signal constellation according to a current retransmission number from the memory, upon receipt of a retransmission request signal from a receiver, and modulates transmission data to complex symbols on the signal constellation.

    摘要： An apparatus and method for transmitting/receiving an random access channel (RACH) signal in a broadband wireless communication system where a total uplink frequency band is divided into M sub-bands are provided. In the RACH transmitting apparatus, a generator generates an access code. A sub-carrier allocator divides the access code into M sub-blocks and allocates each of the M sub-blocks to successive sub-carriers in a sub-band. An inverse fast Fourier transform (IFFT) processor generates an orthogonal frequency division multiplexing (OFDM) symbol by performing an IFFT on the allocated sub-blocks.

    摘要： A method for performing an initial operation of a mobile station (MS) that uses a first frequency band, in a frequency overlay communication system having the first frequency band including a plurality of sub-frequency bands. The method includes performing correlation on a full frequency band in units of the first frequency band, receiving broadcast information through a frequency band having a maximum correlation value, and performing an initial access to a base station (BS) through the frequency band having the maximum correlation value if a frequency bandwidth of the BS acquired from the broadcast information is narrower than or equal to a selected frequency bandwidth of the MS.
