Abstract: The present disclosure includes systems and methods for operating a wireless communication system in multiple modes. The system is configured in a first mode when a transmission interference in a receiver of a wireless device is below a first threshold. The system is configured in one or more intermediate modes when the transmission interference is above the first threshold and below a second threshold. The system is configured in a second mode when the transmission interference is above the second threshold. The one or more intermediate modes activate interference management processes and the wireless device transmits data and receives data simultaneously. In some embodiments, transmission interference may be based on an SINR measurement.

Abstract: A preselect circuit maintains the dynamic range of a received RF input signal during bandpass filtering of the received RF input signal. The preselect circuit includes a Q-deficient passive bandpass filter for coupling to an antenna to receive a received RF input signal. The preselect circuit further includes a Q-enhancement circuit coupled to the Q-deficient passive bandpass filter, wherein the Q-enhancement circuit increases a Q-value of the Q-deficient passive bandpass filter by compensating for resistive inductive losses in the bandpass filter.
