Why does the amplitude of equalized output not match to the
transmitted signal?

Hi,

I run LMS example Simulink file doc_lmseq.slx, in which it uses qam16 output symbols. I find that the equalized output signal is bigger than the transmitted signal. The maximum signal of equalized is 1.3 while the transmitted signal is 0.95.

I add a CMA equalizer to this model. CMA output signal amplitude is smaller than the transmitted signal. The maximum CMA output is about 0.8.

Can you explain it to me? Thanks,
