[Discuss-gnuradio] CMA Equalizer error

Hi, I am trying the CMA equalizer of gnuradio and for understanding I am studying the reference paper  mentioned in the doc as well. I have a question after going through the code- Why the real and imag part of the error signals are being clipped at 1.

float re = gr::clip(error.real(), 1.0); float im = gr::clip(error.imag(), 1.0);

Shouldn't it be "d_modulus" instead of 1.

Regards,

Sam
