8159 normalized value units correspond to TMAX = 3.17 dBm0.
The character signal corresponding to positive input values between two successive decision values numbered n and n+1 (see column 4)
is 255-n, expressed as a binary number.
The value at the decoder is y
x
Bit 1 is a 0 for negative input values.
128
is a virtual decision value.
