摘要： A multi-input multi-output (MIMO) antenna for improving isolation is provided. Split ring resonators (SRRs) are structurally arranged on the lower end of a ground surface between a plurality of antenna patterns spaced apart from each other. Accordingly, permeability of the SRRs has a negative value, which prevents current from flowing between antennas. Consequently, the isolation characteristic of the antennas is improved.

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.

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.
