An apparatus and method for receiving data by a receiver in a communication system are provided. The data reception method includes receiving data from a transmitter over a transmission region including multiple tiles and measuring noise of each of predetermined tiles among the multiple tiles, calculating a total variance of noises of the measured tiles and a variance of tiles according to the measured noises, comparing the calculated total variance with a first threshold, and comparing the variance of each tile with a second threshold, calculating a Log Likelihood Ratio (LLR) using a value according to the comparison result and performing decoding using the calculated LLR. Accordingly, the reception performance is improved by minimizing an influence of noises due to ICI in a communication system having a multi-cell configuration.
