Query: Multiple Antenna Cyclostationary Spectrum Sensing Based on the Cyclic
  Correlation Significance Test   In this paper, we propose and analyze a spectrum sensing method based on
cyclostationarity specifically targeted for receivers with multiple antennas.
This detection method is used for determining the presence or absence of
primary users in cognitive radio networks based on the eigenvalues of the
cyclic covariance matrix of received signals. In particular, the cyclic
correlation significance test is used to detect a specific signal-of-interest
by exploiting knowledge of its cyclic frequencies. Analytical expressions for
the probability of detection and probability of false-alarm under both
spatially uncorrelated or spatially correlated noise are derived and verified
by simulation. The detection performance in a Rayleigh flat-fading environment
is found and verified through simulations. One of the advantages of the
proposed method is that the detection threshold is shown to be independent of
both the number of samples and the noise covariance, effectively eliminating
the dependence on accurate noise estimation. The proposed method is also shown
to provide higher detection probability and better robustness to noise
uncertainty than existing multiple-antenna cyclostationary-based spectrum
sensing algorithms under both AWGN as well as a quasi-static Rayleigh fading
channel.
