| Number | Title | Issue Date |
| 7133480 | Method and apparatus for processing digitally sampled signals at a resolution finer than that of a sampling clock A method and related apparatus for reproducing a periodic signal received over a communication channel, or signal window of a desired profile, wherein the resolution of the reproduced signal or window is not limited by a digital sampling interval. The profile can be... | 11/07/2006 |
| 6363123 | Receiver calibration technique for global orbiting navigation satellite system (GLONASS) A GLONASS receiver and a corresponding method for its calibration for more precise carrier phase measurements. The receiver includes a conventional receiver channel (36), having a bandpass filter (40) for establishing the sampling bandwidth prior to digit... | 03/26/2002 |
| 6163567 | Method and apparatus for code synchronization in a global positioning system receiver An improved method and apparatus for effecting code synchronization in a global positioning system receiver is disclosed herein. Within the receiver, digital in-phase (I) and quadrature (Q) samples of a plurality of received pseudorandom noise (PRN) encod... | 12/19/2000 |
| 6160841 | Mitigation of multipath effects in global positioning system receivers A technique for minimizing or eliminating the effect of multipath signals in a receiver processing pseudorandom (PRN) code signals, such as in a global positioning system (GPS) receiver. The presence of multipath signals adversely affects both code measur... | 12/12/2000 |
