Abstract
Systems, methods, and devices reduce and mitigate spurs that may occur in transmit waveforms of wireless communications devices. Methods include beginning transmission of a portion of a data packet from a baseband layer of a wireless communications device, and generating a spur canceling signal based on an estimated magnitude and an estimated phase of a spur signal at identified spur frequencies of a frequency band used for the transmission. Methods also include subtracting the spur canceling signal from the transmission of the portion of the data packet, and generating a transmitted signal based on the subtracting such that the spur canceling signal is subtracted during the transmission of the portion of the data packet.
