Adjacent-channel interference and spur handling in wireless communications

A wireless communication apparatus comprising:

• a communication interface configured to receive a signal;
• a computer-readable medium comprising an adjacent-channel interference (ACI) handling code;
• and
• at least one processor coupled to the communication interface and the computer-readable medium,
• wherein the at least one processor when executing the ACI handling code, comprises:
• a fast Fourier transform (FFT) block configured to perform a single discrete Fourier transform (DFT) on the signal to generate frequency domain data;
• a sample collector and spur handler (SCSH) block configured to determine respective energy of a plurality of adjacent channels of the signal utilizing the frequency domain data;
• a potential interferer determining block 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;
• and
• a decision pruning block configured to:
• identify one or more dominant interfering channels from among the potential interfering channels;
• and
• detect ACI based on the one or more dominant interfering channels.
