8PSK 8-PSK is usually the highest order PSK constellation
deployed. With more than
8 phases, the error-rate becomes too high and there are
better, though more complex, modulations available such
as quadrature amplitude modulation (QAM).
Although any number of phases may be used, the fact
that the constellation must usually deal with binary data
means that the number of symbols is usually a power of 2
— this allows an equal number of bits-per-symbol.
CAM Conditional Access Module is an electronic device, usually
incorporating a slot for a smart card, which equips an
Integrated Digital Television or set-top box with the
appropriate hardware facility to view conditional access
content that has been encrypted using a conditional
access system. They are normally used with direct
broadcast satellite (DBS) services.
