A method and apparatus for estimating noise in a signal reception apparatus of a communication system are provided. The method and apparatus include a channel estimator for estimating a channel for a signal vector received from multiple cells, and a noise estimator for estimating noise using the received signal vector, a number of the cells, a number of pilot subcarriers used for the channel estimation and pilot patterns used in the cells. As provided, the noise estimation method and apparatus improve decoding performance which improves cell capacity in a communication system.
