    Hello,

    Could someone briefly explain what a "decided signal" is? Is it, f. i.,
    similar to a "selected signal"?

    TIA and have a great day.

    After a little looking around, I found this term in a Sony glossary,
    where the real context should apparently be 'deterministic signal'.

    See http://products.sel.sony.com/semi/glossary.html

    A deterministic signal is used in communications systems (by adding it
    at the transmitter) to permit the receiver to lock to the original
    *information* signal. There are wide varieties of how this is done.
    Note that deterministic signal energy is 'wasted' in terms of
    communications systems - i.e. the system power efficiency is
    transmitted *information* power / total transmitted power.

    I am sure many here could elaborate on deterministic signals (I don't
    have a huge amount of time right now).

    Cheers
