This chapter presents the basics of the current theory regarding the behavior of blind fractionally-spaced and/or spatial-diversity equalizers (FSE) adapted via the constant modulus algorithm (CMA). The constant modulus algorithm , which was developed in the late 1970s and disclosed in the early 1980s, performs a stochastic gradient descent of a cost… (More)

I had stopped the car at a traffic light in the small, suburban New Jersey town of Red Bank. In the time that it took the light to change from red to green, I invented my automatic equalizer.
