Abstract

Systems and methods for providing wireless communication impairment correction using non-linear iterative precoding by a transmitter device are disclosed. The transmitter may exploit the non-linear transmit indications, and perform digital non-linear multiple input multiple output (MIMO) precoding of a transmit signal to improve the error vector magnitude (EVM) at the intended receiver device and/or reduce the adjacent channel leakage ratio (ACLR) at the unintended receiver devices. The non-linear transmit indications may comprise amplitude modulation to amplitude modulation (AM-AM) and amplitude modulation to phase modulation (AM-PM) indications. In operation, the non-linear transmit indications may be received from the intended receiver devices or may be measured by the transmitter device.
