Abstract

There are different ways to perform speech enhancement in the frequency domain from a single microphone signal. The simplest way is to estimate the desired signal from the noisy observation with a simple complex gain. This approach is investigated in this chapter and all well-known optimal gains are derived. We start by explaining the single-channel signal model for speech enhancement in the time and frequency domains.
