Abstract: One example communication device receives a radio frequency (RF) signal. The communication device may include a radio frequency integrated circuit (RFIC) that includes an internal attenuator. The RFIC and other processing circuitry may convert the received RF signal to a baseband frequency to generate a processed complex baseband signal. A digital signal processor of the communication device may determine, based on detection of or lack of detection of distortion terms in a frequency spectrum of the processed complex baseband signal at frequencies corresponding to integer multiples of a symbol rate of a linear modulation interferer, a modulation type of an interferer signal that forms at least part of the processed complex baseband signal. The digital signal processor may also control whether the internal attenuator is enabled based on a received signal strength indication (RSSI) of a desired RF signal and the modulation type of the interferer signal.

Abstract: A very low intermediate frequency receiver and methods for controlling the same. One method includes providing, using a local oscillator, a first intermediate frequency, detecting, using an interferer detector, an adjacent or alternate channel interference signal and an image of the adjacent or adjacent channel interference signal causing interference with a desired signal, and determining, using an electronic processor, whether the desired signal is an analog signal. In response to determining that the desired signal is an analog signal, the method includes controlling, using the electronic processor, the local oscillator to provide a second intermediate frequency. In response to determining that the desired signal is not an analog signal, the method includes determining, using the electronic processor, a switching condition based on the desired signal, and controlling, using the electronic processor, the local oscillator to provide the second intermediate frequency in response to determining the switching condition.

Abstract: A very low intermediate frequency (VLIF) receiver and a method of controlling a VLIF receiver. The method comprises estimating energy levels in first and second signals and detecting interference from a first adjacent channel interferer based upon a difference in energy in the first and second signals. The first signal comprising a first on-channel portion and an adjacent channel portion and the second signal comprises an intermediate frequency translation of the first on-channel portion. The energy levels are estimated for corresponding time instances and the adjacent channel interferer is of the adjacent channel portion. The VLIF receiver is then controlled based upon the detected interference.

Abstract: A device and method for correcting in-phase and quadrature phase (IQ) baseband components to drive a speaker is provided. The device: controls a local oscillator of an RF downmixing device to a plurality of baseband frequency offsets over a range that includes a given baseband frequency offset; determines, at the plurality of baseband frequency offsets, for a received RF signal, amplitude ratio error and phase error for respective IQ baseband components of the received RF signal; generates, using the amplitude ratio error and the phase error for the respective IQ baseband components, for the given offset, filter coefficients for a given baseband frequency range which compensates for respective amplitude ratio error and respective phase error for the given baseband frequency range; and filters, with the filter coefficients, IQ baseband components of the received RF signal, with the local oscillator operating at the given offset, to generate corrected IQ baseband components.

Abstract: A device and method for reducing intermodulation within a radio receiver. The device includes an intermodulation filter. The intermodulation filter is configured to receive a signal, apply a first filter and a second filter to the signal to generate a first and a second filtered signal. The intermodulation filter is configured to isolate a first intermodulation component located on a first side of a frequency spectrum of the signal within the second filtered signal, determine an estimated second intermodulation component based on a potential frequency band location, determine a correction factor based on an amplitude and phase relationship between the first and second intermodulation components, apply the correction factor to the estimated second intermodulation component, determine if the second intermodulation component exceeds a predetermined power threshold, and apply the adjusted estimated second intermodulation component to the first filtered signal, suppressing the second intermodulation component.
