A method of signal compensation in wireless communications is described. The method includes receiving a signal that has been distorted by a transmitter. This signal includes in-band (IB) components that include both data and distortion, and out-of-band (OOB) components that are indicative of distortion. The method includes decomposing the received signal to distinguish between the IB and OOB components. It then uses the content within the OOB components to reduce the distortion and produce a compensated signal. An apparatus and one or more non-transitory computer-readable storage devices configured to perform this method are also disclosed. With the embodiments described herein, improved signal fidelity is achieved, allowing for improved receiver performance without the need for additional reference signals or complex transmitter-side compensation mechanisms.
