The advantage of using the interframe correlation is that we can improve not only the long-time fullband SNR, but the frame-wise subband SNR as well. The third and fourth classes discuss the problem of multichannel noise reduction in the STFT domain with and without interframe correlation, respectively. In the last category, we consider the interband correlation in the design of the noise reduction filters. We illustrate the basic principle for the single-channel case as an example, while this concept can be generalized to other scenarios. In all categories, we propose different optimization cost functions from which we derive the optimal filters and we also define the performance measures that help analyzing them.

From the reviews:
"This work addresses the problem in the short-time Fourier transform (STFT) domain. The general problem is divided into five basic categories depending on the number of microphones being used and whether the interframe or interband correlation is considered. ... This book is mainly a research book for people doing research in electrical and computer engineering." (Yuehua Wu, Zentralblatt MATH, Vol. 1242, 2012)
