L. Stankovic et V. Ivanovic, FURTHER RESULTS ON THE MINIMUM-VARIANCE TIME-FREQUENCY DISTRIBUTION KERNELS, IEEE transactions on signal processing, 45(6), 1997, pp. 1650-1655
Results for the minimum variance kernel, presented by Hearon and Amin,
for the complex Gaussian white noise with independent real and imagin
ary parts remain valid for real noise and approximately valid for anal
ytic noise. These results are extended to the real and analytic noisy
signals cases.
