Handbook of Blind Source Separation: Independent Component Analysis and Blind Deconvolution
Chapter One
IntroductionC. Jutten and P. Comon
Blind techniques were born in the 1980s, when the first adaptive equalizers were designed for digital communications. The problem was to compensate for the effects of an unknown linear single input single output (SISO) stationary channel, without knowing the input.
The scientific community used the word "blind" for denoting all identification or inversion methods based on output observations only. In fact, blind techniques in digital communications aimed at working when the "eye was closed"; hence the terminology.
At the beginning, the word "unsupervised" was sometimes used (for instance in French the wording autodidacte), but it seems now better to be consistent with the worldwide terminology, even if this is not ideal, since comprehensible only in the context of digital communications.
The problem of blind source separation (BSS) differs from blind equalization, addressed previously by Sato, Godard and Benveniste, by the fact that the unknown linear system consists of several inputs and outputs: such a system is referred to as multiple inputs multiple outputs (MIMO). Initially restricted to memoryless channels, the BSS problem now encompasses all linear or nonlinear MIMO mixtures, with or without memory.
The BSS problem was first formulated in 1984, although theoretical principles, which drive source separation methods, were understood later. In this chapter, we briefly introduce the principles and main notations used in this book. A few ideas which contributed to the development of this research domain from its birth are reviewed. The present chapter
