Abstract
A technique for detecting symbols includes performing an over-sized discrete Fourier transform (DFT) operation on a received signal that includes at least two repeated symbols. A sum of signal characteristics for subcarriers of one or more possible symbols are determined based on the DFT operation. A sum of signal characteristics for non-subcarriers of the one or more possible symbols is determined based on the DFT operation. Finally, a determination is made as to whether one or more of the one or more possible symbols is detected based on the sum of signal characteristics for the subcarriers and sum of signal characteristics for the non-subcarriers.
