Abstract
Systems, methods, and devices perform channel interference detection for wireless devices. Methods include receiving a signal at a wireless device, the signal including at least one data subcarrier and one or more guard subcarriers. Methods also include determining, using processing logic, that one or more guard subcarriers are available for adjacent channel interference (ACI) detection, measuring, using the processing logic, a power of each of the one or more guard subcarriers and a total power of the one or more guard subcarriers, and determining, using the processing logic, an ACI is present based, at least in part, on the measurements of the one or more guard subcarriers. Methods further include performing, using the processing logic, one or more deweighing operations based on one or more identified features of the ACI.
