Abstract
This paper provides a tutorial introduction to the constant modulus
(CM) criterion for blind fractionally-spaced equalizer (FSE) design
via a (stochastic) gradient descent algorithm such as
the Constant Modulus Algorithm. The topical divisions utilized in
this tutorial can be used to help catalog the emerging literature on
the CM criterion and on the behavior of (stochastic) gradient
descent algorithms used to minimize it.
