Gps receiver and method for processing gps signals

Abstract From the Canadian patent

A GPS receiver in one embodiment includes an antenna which receives GPS signals at an RF frequency from in view satellites; a downconverter coupled to the , antenna for reducing the RF frequency of the received GPS signals to an intermediate , frequency (IF); a digitizer coupled to the downconverter and sampling the IF GPS signals , at a predetermined rate to produce sampled IF GPS signals; a memory coupled to the , digitizer storing the sampled IF GPS signals (a snapshot of GPS signals); and a digital , signal processor (DSP) coupled to said memory for performing fast convolution. The , digital signal processor processes sampled IF GPS signals by performing a plurality of , fast …
