Circuits, devices, and processes for improved positioning satellite reception and other spread spectrum reception

A receiver for bit-edge-asynchronous detection of a GNSS signal such as Glonass, the receiver comprising:

• a search circuit having an hypothesis-search circuit operable to execute correlations spaced apart a predetermined amount in hypothesis frequency according to multiple staggered coherent integration windows that are co-prime with half a data bit-period;
• and
• a noncoherent integration mechanism for combining across a dwell the results of the correlations spaced apart a predetermined amount in frequency according to multiple staggered coherent integration windows, to find a composite peak corresponding to a Doppler frequency halfway between a pair of such hypothesis frequencies.

An electronic process for spread spectrum signal processing, comprising:

• electronically searching hypothesis frequencies and code lags to produce correlation results;
• electronically combining the correlation results for at least two hypothesis frequencies at a given code lag, the frequencies separated by a predetermined frequency difference, and to identify a peak in the correlation results.
