摘要：
A GPS receiver architecture is disclosed having digital correlation processing in faster than real-time, which is achieved by storing signal samples into a memory in real-time at a first rate and reading packs of stored samples at a second higher rate. For mitigating cross-correlation interference from the strong signal to reception of weak ones, a group of compensator blocks is introduced. A method of interference waveform reproducing is disclosed that compensates influence of stronger signal over long coherent accumulation intervals, not complicating processing of the strong signal over shorter coherent accumulation intervals. Search bins corrupted by under-compensated interference are pre-calculated and discarded.
