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.
