As stated, I suggest that SE-CMA obtains better performance than CMA 2-2 when a BPSK source is used. Specifically, I propose that the SE-CMA minima conincide more closely with MMSE minima when the source alphabet is BPSK. Here are several examples that illustrate this claim. Most of these examples are constructed with two-tap FSE's; this enables visualization of the cost surface in equalizer-coefficient space.
