Transmit spur detection and mitigation for wireless communications devices

A system comprising:

• a transceiver configured to transmit and receive data based on one or more wireless communications protocols;
• and
• a processing device comprising one or more processors configured to:
• receive a plurality of samples of a transmitted signal from the transceiver;
• generate an estimated amplitude and an estimated phase of a spur component of the transmitted signal based on the received plurality of samples, the spur component being a spectral spike in a transmit waveform, the estimated amplitude and estimated phase being generated by a first correlator and a second correlator using a first reference signal and a second reference signal;
• generate a canceling signal configured to cancel the estimated amplitude and estimated phase of the spur component;
• and
• cancel the spur component of the transmitted signal by combining the canceling signal with a transmission of the transmitted signal.

A computer program product comprising non-transitory computer-readable program code capable of being executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code comprising instructions configurable to cause the one or more processors to perform a method comprising:

• receiving a plurality of samples of a baseband transmission;
• generating, using a processing device, an estimated amplitude and an estimated phase of a spur component of the baseband transmission based on the received plurality of samples, the spur component being a spectral spike in a transmit waveform, the estimated amplitude and estimated phase being generated by a first correlator and a second correlator using a first reference signal and a second reference signal;
• generating, using the processing device, a canceling signal configured to cancel the estimated amplitude and estimated phase of the spur component;
• and
• canceling the spur component of the baseband transmission by combining the canceling signal with a transmission of at least a portion of a data packet.
