Abstract
The use of differentially coherent combining is proposed
to improve the performance of a double-dwell acquisition
system by increasing the reliability of a decision in the verification
stage. The detection and mean acquisition time performance of the
acquisition scheme with the proposed combining scheme is analyzed
in frequency-selective Rayleigh fading channels, and compared
with that of two previously published double-dwell acquisition
schemes based on long correlation intervals and noncoherent
combining. It is shown that the proposed acquisition scheme outperforms
the previous ones, and that the performance improvement
increases as the frequency offset increases.
