摘要： Techniques are provided for fine-tuning estimates of a delay value for a sampled signal. One aspect of the invention is to perform, for the sampled signal, coarse-grained calculations of the In Phase and Quadrature (I and Q) correlation integrals at a limited number of points, wherein the calculations are performed over a range of hypothesized delay values. A range of delay values of interest are then determined from the coarse-grained calculations of the I and Q correlation integrals. A subset of I and Q values based on the coarse granularity calculations of the I and Q correlation functions is used to perform a time-domain interpolation to obtain fine-grained values of the I and Q integrals in the range of the delay values of interest. Magnitude calculations are performed based on the fine-grained values of the I and Q integrals. Fine-tuned estimates of delay value are based on the magnitude calculations. Alternatively, fine-tuned estimates of delay value are based on the template-matching approach.

摘要： Techniques are provided for determining clock doppler of a signal receiver. One aspect of the invention is to divide sampled data received from a receiver into data segments of incremental length. The clock doppler is estimated based on each data segment with respect to all the satellites from a set of satellites that is overhead the receiver. For each data segment , the results with respect to each satellite is used to refine the calculations of the clock doppler with respect to the next satellite. When the clock doppler calculations have been performed using all the satellites from the set of satellites for a particular data segment , then the results with respect to the particular data segment is used to refine the calculations of the clock doppler with respect to the next data segment .
