Radial mean square error value *10 in dB. Radial MSE is a method for estimating the signal to noise ratio. ACM engine uses normalized MSE, which is the inverse of SNR. It is calculated by dividing the estimated MSE level with the energy of the received constellation. Radial MSE peak value threshold is dependent on modulation used and LDPC code rate. In case of QPSK it is -8 dB (-10.5 for 'wide'), 16APSK - -13 dB (-18 for 'wide') and 32APSK - -15.5 dB (-21.5 for 'wide'). If the value trespasses this threshold, BER at the output of LDPC decoder will reach the value of 1.0e-06.
