摘要： Embodiments of a low intermediate frequency system and method are disclosed. In one embodiment, among others, a method for operating a receiver is disclosed that comprises receiving a radio frequency signal, downconverting the radio frequency signal to a downconverted signal comprising an in-phase component and quadrature-phase component, buffering the downconverted signal in a memory, estimating receiver impairments associated with the in-phase component and the quadrature-phase component for a defined time period, and compensating for the receiver impairments for each defined time period.

摘要： A multi-band communication device configured with a mobile communication device for voice or data communication over a cellular, satellite or other communication network and configured with an auxiliary communication system configured to receive and/or transmit an auxiliary communication signal. The mobile communication device and auxiliary communication system are integrated into the same components within the multi-band communication device thereby allowing the components to share the processing tasks associated with each communication device within the multi-band communication device. The auxiliary communication device may be configured to operate during standby mode of the mobile communication device, such as during reception of a paging signal. The auxiliary communication device may comprise, but is not limited to, AM or FM radio, personal communication devices such as FRS, GMRS, or weather band radio.

摘要： A DC offset detection and cancellation system for a receiver is disclosed. The DC offset detection and cancellation system comprises a downconverter configured to downconvert a received signal to a baseband level signal, the downconverted signal having a first sampling rate, a filter system configured to filter the downconverted received signal at the first sampling rate, and estimator logic configured to sample the downconverted received signal at the first sampling rate to develop a DC estimate signal representative of any direct current (DC) component present on the downconverted received signal, the filter system configured to develop a second sampling rate, where the first sampling rate is significantly higher than the second sampling rate.
