Abstract: Aspects of the present disclosure provides a wireless communication apparatus configured to handle adjacent-channel interference (ACI) and spur. The apparatus receives a signal utilizing a communication interface. The apparatus is configured to perform a single discrete Fourier transform (DFT) on the signal to generate frequency domain data. The apparatus is further configured to determine respective energy of a plurality of adjacent channels of the signal utilizing the frequency domain data. The apparatus is further configured to determine one or more potential interfering channels among the adjacent channels, wherein each of the potential interfering channels has an energy greater than a qualifying threshold. The apparatus is further configured to identify one or more dominant interfering channels from among the potential interfering channels. The apparatus is further configured to detect ACI based on the one or more dominant interfering channels.
