Abstract: A radio receiver processing path has a mixer with active interference/blocker cancellation to reduce the intensity of leaked and undesired signals by using a replica of the transmitted signal, emulating the phase and attenuation through the leakage path and subtracting the emulated signal within the mixer. Intermodulation distortions are predicted through the use of nonlinear modeling in the digital baseband between the baseband transmitter and baseband receiver and subsequently subtracted from the received signal. The nonlinear basis functions are combined to model the composite nonlinearity in the signal path based on digital baseband transmitted data. The modeled nonlinearity is subtracted from the received signal, and the result is observed and used to guide the nonlinear modeling parameters using self-contained control loops.

Abstract: Automatic recalculation of tuner filter coefficients are made in order to compensate for changes in signal properties due to processing functionality in the tuner. The architecture compensates for processing changes, such as a large continuous range of clock frequency shifts, while not sacrificing bandwidth response characteristics of the channel filter. Embodiments may calculate coefficients in order to obtain response characteristics while utilizing a completely on-chip architecture, which does not require accessing off-chip software driver programs, and does not require complex look-up tables containing filter coefficients stored in onboard memory.

Abstract: An air pump assembly includes a pump module having an outer surface and a casing at least partially surrounding the pump module. The casing has an inner surface defining a cavity sized to snugly receive the pump module such that the outer surface of the pump module is in substantial engagement with the inner surface of the casing and is substantially prevented from moving with respect to the casing when the pump module is received within the cavity. At least one airflow passageway is defined between the inner surface of the casing and the outer surface of the pump module. The airflow passageway is configured so that air flowing through the passageway changes direction at least one time to reduce the transmission of noise from the air pump assembly.
