Further results on the minimum variance time-frequency distribution kernels
Ljubiša Stanković, Veselin N. Ivanović · IEEE Transactions on Signal Processing · 1997
Results for the minimum variance kernel, presented by Hearon and Amin (see ibid., vol.43, p.1258, 1995), for the complex Gaussian white noise with independent real and imaginary parts remain valid for real noise and approximately valid for analytic noise. These results are extended to the real and analytic noisy signals cases.
