Abstract
This project has accomplished research
work for the development of the theory in
evaluating the performance of (1) the
conventional SCORE algorithms and (2)
conjugate cyclic MUSIC in the presence of
cycle frequency error (CFE) regarding the
Signals Of Interest (SOI). Using the theory of
Fourier transform, the problem formulation
for the SCORE algorithms under CFE has
been completed. This results in an analytical
formula which demonstrates the behavior of
the performance degradation for the SCORE
algorithms. It is shown that the output SINR
of an adaptive array beamformer using the
SCORE algorithms deteriorates like a sinc
function as the number of data snapshots
increases. The similar problem for conjugate
cyclic MUSIC has been also completed.
From the theoretical analyses, we note that
the performance of the conjugate cyclic
MUSIC also degrades like a sinc function as
the number of data snapshots increases. The
validity of the obtained theoretical results is
demonstrated by several simulation
examples.
