Abstract
A wireless communication device includes one or more transmitter (TX)-receiver (RX) pairs, one or more RX distortion estimators, and a combiner. A first RX distortion estimator receives a first TX signal corresponding to a first TX of the first TX-RX pair and a second TX signal corresponding to a second TX of a second TX-RX pair. The first RX distortion estimator processes the first TX signal and the second TX signal based on a first base function set including at least one base function to generate a first distortion signal set including at least one distortion signal. Then, the first RX distortion estimator processes the first distortion signal set to generate a first RX correction signal. The wireless communication device's combiner generates a first distortion compensated RX signal by compensating for distortion in a first RX signal of the first TX-RX pair based on the first RX correction signal.
