Abstract
Two classes of algorithms for multichannel blind equalization are
the mutually referenced equalizer (MRE) method by Gesbert et al. (see
ibid. vol.45, p.2307-17, 1997) and the subspace intersection (SSI)
method by van der Veen et al. (see ibid., vol. 45, no.1, p.173-90,
1997). Although these methods seem, at first sight, unrelated, we show
that certain variants of the SSI and the MRE methods both optimize a new
blind criterion, which is referred to as maximum coherence and, thus,
are equivalent
