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： The correlation circuitry of the present invention operates in communication with a controller and transform circuitry to concurrently search a range of frequencies by correlating a received signal from the global positioning system (GPS) with a generated frequency and a generated code at a plurality of time offsets. The output of the correlation circuitry is provided to the transform circuitry, such as fast Fourier transform (FFT) circuitry, that transforms the output of the correlation circuitry. The results from the transformation circuitry are used by a GPS receiver to determine a frequency of the received GPS signal and a time offset associated with a ranging code carried in the received GPS signal.

摘要： The address translation logic of the present invention is incorporated in a global positioning system (GPS) receiver and operates to group data in memory based on translating the address from a direct memory access controller. The data includes post-correlated samples of the correlation of a signal with a generated frequency and a generated code having a plurality of time offsets. In general, the address translation logic organizes the data such that each element of the data associated with particular ones of the plurality of time offsets are grouped together in order to improve the efficiency of performing a fast Fourier transform of the data. In addition, the address translation logic allows the transfer of data from correlation circuitry to memory, from the memory to an FFT module, and from the FFT module to the memory using standard DMA controllers.
