摘要：A signal processor for GPS or other GNSS radiolocalization systems, includes a•RAM pre-correlation buffer (37) which is filled with samples which are generated by asampling stage (35) whose sampling rate is governed by a programmable oscillator (350)which is set according to the Doppler shift of a satellite whose acquisition is intended, insync with the code NCO. Thus all sample alignment in the buffer is fixed. The devicefurther includes an amplitude compressor (36) to limit the size of the buffer memory andis optimized to provide data to the following DFT unit (60) in small bursts thatcan beprocessed in real time without the need for intermediate buffers. Thanks to thesefeatures the processor limits the amount of fast intermediate memories, is simpler andhas lowerpower consumption.
