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 (CMA). The topical divisions utilized in this tutorial

This paper reports on the gathering, processing, and categorization of empirically derived time-varying channel responses. The passband data and datu collection information is provided courtesy of Applied Signal Technology (Sunnyvale, CA). It is the intent of this paper to provide the signal processing community with a database of timevarying fractionally-spaced channel responses and received sequences based on empirical measurements which can be used to test and refine existing time-varying channel models and also propose new ones.
