Techniques are provided for generating pre-correlation phase coherent samples that can be used with coherent integration. Samples received over a buffer duration are equally divided into sub-buffers. A pre-correlation accumulation (PCA) output is generated, for each of a plurality of different test Doppler remainders of an unknown Doppler shift, using different multiples of the Doppler remainder being tested. A differential operation, to mitigate the Doppler shift, is executed on the PCA output for a test Doppler remainder, and the PCA output is mixed with a delayed version of itself to generate a PCA differential result. Signal despreading is executed by mixing the PCA differential result with a code matching differential result to generate a despreading result. Coherent integration is executed by accumulating the despreading result to generate a correlation output. If the correlation output meets a predefined threshold, signal detection is confirmed.
