    摘要： A system and method for transmitting and receiving a signal in a communication system using a relay scheme. A base station receives a first signal in a first time interval from a first mobile station which is at least one mobile station located in a third region which is a region where a first region which is a region of the base station itself overlaps with a second region which is a region of a relay station. The relay station receives a second signal in the first time interval from a second mobile station which is at least one mobile station located in a fourth region which is a region not overlapping with the first region in the second region, and receives the first signal from the first mobile station. The relay station transmits a third signal including the first signal and the second signal to the base station in a second time interval. The base station receives the third signal in the second time interval, and cancels the first signal from the third signal to detect the second signal.

    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： Provided is a method and apparatus for transmitting/receiving data in a frequency overlay communication system. A transmitter generates a data stream for data transmission, and performs Inverse Fast Fourier Transform (IFFT) on the generated data stream according to a predetermined first frequency band before transmission. Upon receiving a particular signal, a receiver performs Fast Fourier Transform (FFT) on the received signal according to a predetermined second frequency band, and restores the received signal.

    摘要： Disclosed is an apparatus for transmitting a bit-interleaved coded modulation (BICM) signal in an orthogonal frequency division multiplexing (OFDM) system. A serial-to-parallel (S/P) converter generates bit streams using coded bits according to the number of transmission antennas and a modulation order of a predetermined modulation scheme. An interleaver applies at least one offset to the bit streams and performs interleaving on the offset-applied bit streams. A combiner combines the interleaved bit streams according to the number of transmission antennas.
