    Abstract: An apparatus and a method for composing a diversity sub channel in a wireless communication system are provided to compose a diversity channel for a diversity gain in a wireless resource. A diversity sub channel of a resource allocation unit is composed by performing permutation of a resource allocation unit about resources allocated for the diversity sub channel. The resource allocation unit is a PRU(Physical Resource Unit). When a diversity sub channel of a tone unit is composed, resources for the diversity sub channel of a tone unit is checked among resources to which permutation of the resource allocation unit is applied. The diversity sub channel of the tone unit is composed by performing permutation of a tone unit about the checked resources(813).

    Abstract: A method and an apparatus for transmitting and receiving a signal in a communication system using an HARQ(Hybrid Automatic Repeat request) method are provided to transmit and receive a signal using various coding rates. A signal transmission apparatus includes an encoder(311), a modulator(313), and a transmitter(315). The encoder generates the codeword vector by encoding an information vector using a first parity check matrix of an LDPC(Low Density Parity Check) code. A modulator generates a codeword vector to a modulation vector using a modulation method and outputs the modulation vector to the transmitter. The transmitter processes the codeword vector and transmits the transmission vector after generating the transmission vector. A first parity check matrix includes a plurality of square matrix rows. The first parity check matrix is one among the p parity check matrixes stored in the signal transmission apparatus. The p parity check matrixes support the number of the different information vector square matrix rows respectively.

    Abstract: A method and an apparatus for transmitting and receiving a reference signal in a communication system are provided to estimate a channel accurately using the pilot tones transmitted to the different transmission power value even though the non-uniformity of the power is generated. Map messages, data tones, and pilot tones are generated in a sub frame unit(601). A first transmission power value and a second transmission power value of the first and second pilot tones positioned on one resource among the same frequency resource and the same time resource among the pilot tones included in the data area inside the sub frame comprised of the time and frequency resources are differently determined(603). Weights are determined to correspond to the data areas by considering the transmission power values corresponding to the determined data areas(605). A signal is generated by mapping the map messages, the data tones, and the pilot tones(609). After the generated signal is inverse fast Fourier transformed, the signal is transmitted to the receiver through an antenna(611). The first transmission power value is a reference transmission power value. The second transmission power is the transmission power value determined by multiplying the reference transmission power value by the weight.
