What is probabilistic signal?
Abstract: A scheme is proposed that combines probabilistic signal shaping with bit-metric decoding. The transmitter generates symbols according to a distribution on the channel input alphabet. The symbols are labeled by bit strings.
What is a deterministic signal?
Signals that can be modeled exactly by a mathematical formula are known as deterministic signals. Deterministic signals are not always adequate to model real-world situations. Random signals, on the other hand, cannot be described by a mathematical equation; they are modeled in probabilistic terms.
