摘要： A global navigation satellite system (GNSS) receiver may be operable to quantize two-dimensional GNSS sample data with an in-phase (I) and quadrature (Q) pair to two-dimensional quantized data with a magnitude and angle pair using the polar quantization, for example, an unrestricted polar quantization. The GNSS receiver may be operable to reduce a size of the two-dimensional quantized data for storage by representing the two-dimensional quantized data by the one-dimensional symbol data. The one-dimensional symbol data may be stored in a random access memory (RAM) for further processing. The I and Q pair associated with the one-dimensional symbol data stored in the RAM may be retrieved and processed by the GNSS receiver using a correlation such as a fast Fourier transform (FFT) correlation.

摘要： A direct-sequence spread spectrum (DSSS) receiver may be operable to process signal samples in frequency domain utilizing a prime factor fast Fourier transform (FFT) circuit and a pseudorandom noise (PRN) code. The DSSS receiver may be operable to transform the signal samples into FFT signal samples using the prime factor FFT circuit, transform the PRN code into a FFT PRN code using the prime factor FFT circuit and multiply the FFT signal samples with the FFT PRN code using the prime factor FFT circuit. The DSSS receiver may be operable to inversely transform the multiplied FFT signal samples into correlated signal samples using a prime factor inverse FFT (IFFT) implemented by the prime factor FFT circuit. The prime factor FFT circuit may comprise a prime length FFT core, a FFT memory, a register bank, a switch, a multiplier and a FFT controller.

摘要： A global navigation satellite system (GNSS) enabled mobile device may be operable to monitor and determine counts at which autoblank signals are asserted over time intervals corresponding to consecutive time windows during the RF interference mitigation process using autoblanking. The GNSS enabled mobile device may be operable to disable the generation of a blank signal when the count may be greater than a particular count threshold at the end of the time window. The GNSS enabled mobile device may be operable to enable the generation of a blank signal when the count may be less than or equal to a particular count threshold at the end of the time window. The blank signals may be used to blank the processing of the received GNSS signals.

摘要： A global navigation satellite system (GNSS) enabled mobile device may be operable to assert one of autoblank signals when RF interference is detected in received GNSS signals for one of consecutive first time windows. The asserted autoblank signals are monitored by the GNSS enabled mobile device over time intervals corresponding to consecutive second time windows and a rate at which the autoblank signals are asserted for each of the consecutive second time windows is determined by the GNSS enabled mobile device based on the monitoring. The GNSS enabled mobile device may be operable to determine whether to blank processing of the received GNSS signals based on the determined rate. The autoblank signals may be asserted by the GNSS enabled mobile device based on a number of the received GNSS signals whose absolute signal levels exceed a signal level threshold for the first time window.
