Résumé:
This paper derives the optimal single input multiple output
(SIMO) maximum likelihood sequence estimation (MLSE)
receiver for the detection of quadrature amplitude modula-
tions corrupted by potentially noncircular, stationary white or
colored zero-mean Gaussian noise. It is proved that this re-
ceiver is composed by a widely linear (WL) filter followed
by a modified version of the Viterbi algorithm. This WL lin-
ear filter is interpreted for complex-valued signal of interest
(SOI) symbols as two WL multidimensional matched filter
(WL MMF) that reduce to a single WL MMF for real-valued
SOI symbols. The performance’s improvements of this re-
ceiver with respect to the standard SIMO MLSE are proved
and illustrated
