Patent number: 8520717Abstract: Radiolocalization receiver having a plurality of correlation taps, and including a module of cross-correlation detection in which spurious correlation terms are detected by statistical analysis of the frequencies of the candidate peaks. The system can restrict further integration to those taps whose frequency is outside the cross-interference signal, or trigger new acquisition of different space vehicles, upon detection of a cross-interference situation.Type: GrantFiled: October 10, 2007Date of Patent: August 27, 2013Assignee: QUALCOMM IncorporatedInventors: Joel Brenner, Angelo Genghi

Patent number: 8362952Abstract: Radiolocalization receiver with a massively parallel array of correlators, comprising a data compression module (199) to compress the incoherent integration values accumulated into the incoherent integration memories (176). By compressing incoherent integration values, relevant memory saving can be obtained or, in alternative, loss of data by excessive prescaling can be avoided or attenuated. The invention proposes a simple compression scheme based on offset subtraction which allows save memory size.Type: GrantFiled: February 26, 2010Date of Patent: January 29, 2013Assignee: QUALCOMM IncorporatedInventor: Joel Brenner

Patent number: 7966359Abstract: A Frequency discriminator based on a combination of Discrete Fourier Transform (DFT) operator and half-bin DFT operator, corresponding to a set of Twiddle factors with frequency double than the sampling frequency. The frequency estimators are so chosen as not to have any zero or discontinuity point. Therefore the discriminator of embodiments of invention is more stable and well-behaved in an extended operating range. The discriminator of the invention, when applied to a Global Positioning System (GPS) receiver, allows a safer lock to the carrier frequency, even in presence of a large initial error, and avoids the problem of false locks.Type: GrantFiled: March 20, 2007Date of Patent: June 21, 2011Assignee: Qualcomm IncorporatedInventor: Joel Brenner

Patent number: 7843228Abstract: Frequency discriminator based on a variant of the DFT transform in which the usual twiddle factors are replaced with twiddle factors as for a DFT on a number of points which is the double as the actual number of sample points. The DFT so modified allows half-bin frequency discrimination, with few added computational burden. Two DFT shifted of half bin with respect to the zero frequency provide a linear response of the discrimination and good immunity to noise. The discriminator is particularly useful in FLL for tracking signals in a GPS receiver.Type: GrantFiled: May 4, 2009Date of Patent: November 30, 2010Assignee: QUALCOMM IncorporatedInventor: Joel Brenner

Publication number: 20100245170Abstract: A GNSS receiver interfaceable to a host, in which the search functions in the acquisition phase are carried out by the host's resources. The receiver provides correlation samples to the host system by a dedicated high-speed interface, preferably a DMA interface.Type: ApplicationFiled: December 22, 2008Publication date: September 30, 2010Applicant: QUALCOMM IncorporatedInventor: Joel Brenner

Patent number: 7643542Abstract: Acquisition method for a localization receiver, in particular for a Global Positioning System (GPS) receiver. It involves the calculation of an interpolated Fast Fourier Transform (FFT) spectrum (S?) of correlated signals in which the frequency lines corresponding to half-integer values of the frequency resolution defined by the FFT are obtained by a combination of both amplitude and phase values of the FFT spectrum (S).Type: GrantFiled: January 31, 2006Date of Patent: January 5, 2010Assignee: Qualcomm IncorporatedInventor: Joel Brenner

Publication number: 20090213912Abstract: An improved GNSS or GPS receiver with a code-tracking loop comprising a plurality of correlators, arranged to extract a plurality of samples of the autocorrelation function of the C/A code, and a discriminator performing linear regression on both sides of the autocorrelation peak, to determine the autocorrelation peak position at the crossing point of two straight lines. The lines are independently adapted to the sides of the correlation peak and, therefore, the receiver can handle well multipath situations, in which the correlation peaks are distorted.Type: ApplicationFiled: November 24, 2008Publication date: August 27, 2009Inventor: Joel BRENNER
