发明名称 Baseband transmitter self-jamming and intermodulation cancellation device
摘要 <p>Some embodiments provide a method, system, and apparatus for interference cancellation at the baseband of a receiver. A wireless communication device, having a transmitter and receiver, is provided with an adaptive circuit that cancels interference caused by transmit signals (or other signals) leaked or bled onto the receiver at baseband to facilitate detection of a received signal of interest. Some implementations provide for a circuit that approximately reconstructs the second and third order components caused by the nonlinear response of the down-conversion chain of a receiver. This reconstructed signal is then subtracted from the composite received signal to obtain a received signal of interest.</p>
