The apparatuses and methods include receiving, by a receiver device in a WLAN, a distort- ed signal corresponding to a data packet signal transmitted from a transmitter device, receiving, by the receiver device, one or more transmitter parameters corresponding to the transmission of the data packet signal, the one or more transmitter parameters including information to adjust the distorted signal, and adjusting, by the receiver device, the distorted signal to reconstruct the data packet signal based at least on the one or more transmitter parameters.
