Interference cancellation using interference magnitude and phase components

A communication device comprising:

• a processor unit;
• and
• an interference cancellation unit coupled with the processor unit, the interference cancellation unit configured to:
• estimate an interference magnitude component based, at least in part, on a magnitude polynomial expansion and a transmit signal of the communication device;
• estimate an interference phase component based, at least in part, on a phase polynomial expansion and the transmit signal, wherein the magnitude polynomial expansion and the phase polynomial expansion have different polynomial terms;
• determine an interference signal based, at least in part, on the interference magnitude component and the interference phase component;
• and
• cancel at least a portion of the interference signal from a receive signal received by the communication device.
