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.
