摘要： A transmission method based on a Hybrid Automatic Repeat Request (HARQ) scheme for in a communication system. A codeword is generated using a Low Density Parity Check (LDPC) code. Parity bits of the codeword are classified on a basis of a transmission priority. Parity bits with an identical transmission priority are grouped. An information bit group of the codeword and parity bit groups with the identical transmission priority are shuffled in a predefined pattern. A packet is generated from the shuffled information bit group and the shuffled parity bit groups based on the transmission priority. The generated packet is retransmitted in response to a retransmission request. The transmission method can obtain the effect of channel interleaving by setting a transmission priority according to importance of puncturing target blocks, shuffling blocks with the same priority, and shuffling and transmitting bits configuring each block.

摘要： Provided is a two-dimensional equalization method in a receiver of a communication system using an Orthogonal Frequency Division Multiple Access (OFDMA) scheme. The receiver sets as a first value a value of a 1-tap frequency domain equalizer (FEQ) corresponding to a sub-channel allocated to the receiver , and sets as a second value a value of a 1-tap FEQ corresponding to sub-channels other than the allocated sub-channel. Upon receipt of a signal, the receiver performs Fast Fourier Transform (FFT) on the received signal, and equalizes the FFT-processed signal according to the values of the 1-tap FEQs.
