Abstract
A novel acquisition scheme that utilizes multipaths
to improve acquisition performance is proposed for frequency-selective
fading channels. The proposed acquisition scheme employs
nonconsecutive search and joint triple-cell detection. The performance
is analyzed in frequency-selective Rayleigh fading channels.
Equations for the probabilities of detection and false alarm are derived,
and an expression for the mean acquisition time is developed.
The mean acquisition time performance of the proposed and
conventional acquisition schemes is evaluated and compared. It is
found that the proposed acquisition scheme significantly outperforms
the conventional one. The effects of various channel parameters
such as the number of resolvable paths, the shape of the multipath
intensity profile (MIP) and the signal-to-interference ratio
(SIR) on acquisition performance are also investigated.
