In this paper, we focus instead on the performance of Linear Equalizers for fading
channels when they are based on blind channel estimates. Our analysis
shows that with Zero Forcing Linear Equalizer (ZF-LE) at least
one order of the diversity is lost depending on the way by which
the scalar ambiguity that results from the blind channel estimation
is resolved. However, in some Tx scenarios we are able to recover
the diversity with MMSE-LE. Various Tx scenarios are considered
in detail.
Traditionally, the performance of blind SIMO channel estimates has
been characterized in a deterministic fashion, by identifying those
channel realizations that are not blindly identifiable.
