ABSTRACT:
Disclosed is a method for receiving a signal by a receiver in a communication system, the method includes receiving a signal; estimating a first noise value by using a reference signal included in the received signal; estimating a second noise value by using at least one subcarrier which has been unused for a transmission of data and the reference signal; and when a difference between the estimated first noise value and the estimated second noise value is greater than a threshold value, demodulating the data by using an interference removal algorithm.
