Signal detection in OFDM system

A solution for signal detection in a radio receiver receiving multicarrier signals is disclosed. According to the provided solution, the radio receiver receives a radio signal and converts the received radio signal into digital samples. Since a desired signal being detected occupies only a portion of subcarriers of a signal the radio receiver is configured to receive, the received signal is heavily oversampled. A detection procedure may be simplified by utilizing this oversampling. A relation between the known total bandwidth of the desired signal and the total bandwidth of the received radio signal may be calculated, and utilized in the actual signal detection. The signal detection is based on sliding correlation in which the samples of the received signal are correlated with a reference signal with different phase shifts between the two signals. As the result of the correlation, the received signal is determined to be either the desired signal or noise.
