A radio frequency (RF) receiver and method of controlling an RF receiver are provided. The method includes receiving an RF signal and down-converting the RF signal to a substantially baseband signal. A direct current (DC) transition is detected in a portion of the substantially baseband signal. The substantially baseband signal is then filtered using a first filter configuration at the portion of the substantially baseband signal including the DC transition and a second filter configuration at a portion of the substantially baseband signal not including the DC transition.

Interference detection and mitigation in radio frequency receivers

A method of expanding a capacity of a single radio channel, and a radio. The method includes receiving a primary signal and a secondary signal. The method also includes a transmitter modulating the primary signal and the secondary signal. The method further includes the transmitter scaling a power of the secondary signal below a power of the primary signal to create a power differential. The method also includes the transmitter offsetting a carrier frequency of the secondary signal from a carrier frequency of the primary signal to create a carrier frequency offset. The method further includes the transmitter combining the primary signal and the secondary signal to generate a composite signal. The method also includes the transmitter transmitting the composite signal within the single radio channel via an antenna. The antenna is coupled to the transmitter.
