Description: Presently FFT usage in GPS receivers has been a
topic of extensive study and many improved FFT-based
acquisition methods with averaging correlation
technique also have emerged. Although averaging
arithmetic can reduce the instant processing points of
FFT/IFFT, their noise performance is not promising. In
this paper a novel compress-sampling algorithm for
FFT-base GPS signal acquisition method is proposed.
It not only diminishes the size of FFT/IFFT core but
also enhances the noise immunity of receiver with its
“redundancy” structure. Simulation results of Matlab
testify that the computational complexity of the novel
algorithm has been efficiently suppressed to only
0.93 over the 2D search method in time domain. At
the same time the lower amplitude threshold obtained
from the novel method gets a lower false alarm
probability comparing with the direct DFT algorithm
with no compression. The noise immunity is enhanced-Presently FFT usage in GPS receivers has been a
