 PAM-5: Two bits of the binary data are used. The same mapping as for the
PAM-4 modulation is applied to get the 4 outer levels. The level in the
middle is generated randomly with 1/5th probability.
 PAM-10 (or PAM-12): 4 bits of the binary data are used. This gives 16
possible levels. However, only 10 (or 12) values are needed. If the value is
lower than 10 (or 12), direct mapping is applied. If the value is equal to or
greater than 10 (or 12), random mapping is applied to any of the valid 10
(or 12) levels.
