Abstract
The representative embodiments discussed in the present disclosure relate to techniques in which a transmitter may operate in an uplink multiple-input, multiple-output (MIMO) mode of operation. More specifically, in some embodiments, the transmitter may concurrently transmit a first and a second signal within the same frequency band via a first and second antenna, respectively. Further, in some embodiments, the transmitter may include circuitry and/or logic to offset nonlinear interference present in the transmitted signals as a result of antenna coupling between the first and second antenna and a nonlinear element (e.g., a power amplifier) within the transmitter.
