Abstract: A global navigation satellite system (GNSS) receiver includes an internal signal processor configured to perform an internal signal processing operation on a satellite signal to generate satellite information, a switching circuit configured to transmit the satellite signal to the internal signal processor, and a control circuit configured to receive a blanking signal from an external communication device instructing that the internal signal processing operation is to be blocked, and configured to output control information for reducing transmission power of the external communication device and to control the switching circuit to transmit the satellite signal to the internal signal processor regardless of the blanking signal when a frequency at which the blanking signal is received exceeds a reference value.

Abstract: An electronic device, a method, and a chipset for receiving global navigation satellite system (GNSS) signals are provided. The electronic device includes a processor configured to: downconvert, by an input/output (I/O) mixer including a first multiplier and a second multiplier, a modulated radio frequency wave to an intermediate frequency, where the modulated radio frequency wave is input to first inputs of the first multiplier and the second multiplier, and where an in-phase signal and a quadrature phase signal based on a square wave are input to second inputs of the first multiplier and the second multiplier, respectively; filter the downconverted modulated radio frequency wave; and convert the filtered downconverted modulated radio frequency wave to a digital signal.

Abstract: An electronic device, a method, and a chipset for receiving global navigation satellite system (GNSS) signals are provided. An input/output (I/O) mixer including a first multiplier and a second multiplier downconverts a modulated radio frequency wave to an intermediate frequency. The modulated radio frequency wave is input to first inputs of the first multiplier and the second multiplier, and where an in-phase signal, from a first digital to analog converter (DAC), and a quadrature phase signal, from a second DAC, are input to second inputs of the first multiplier and the second multiplier, respectively. A mixer imbalance between the first mixer and the second mixer is reduced using direct current (DC) bias voltages from the first DAC and the second DAC. The DC bias voltages are determined based on a first and second DAC codes of the first and second DACs. The downconverted modulated radio frequency wave is filtered.

Abstract: An apparatus and a method are provided. The apparatus includes a receiver configured to receive a signal over channels, a channel estimator configured to estimate the channels as first channel estimates; and a processor configured to compress the channel estimates to reduce buffer size. The method includes receiving a signal over channels by a receiver, estimating, by a channel estimator, the channels as a first channel estimate; and compressing, by a processor, the channel estimates to reduce buffer size.
