Single-Channel Noise Reduction in the STFT Domain with Interframe Correlation

In the previous chapter, we studied single-channel noise reduction in the time domain. In this chapter, we study the same problem but in the more convenient short-time Fourier transform (STFT) domain. Contrary to most conventional approaches, we do not assume here that successive STFT frames are uncorrelated. As a consequence, the interframe correlation is now taken into account and a filter is used in each subband instead of just a gain to enhance the noisy signal.
