==DEMODULATION OF MODULATION CONSTELLATIONS WITH PROBABILISTIC AMPLITUDE SHAPING - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18547682 titled 'DEMODULATION OF MODULATION CONSTELLATIONS WITH PROBABILISTIC AMPLITUDE SHAPING

==Simplified Explanation==

The patent application describes methods, systems, and devices for wireless communications using probabilistic amplitude shaping (PAS) modulation techniques. Here are some key points to explain the innovation:

* Receiving devices like base stations or user equipment can receive input signals modulated with PAS modulation.
* The receiving device determines a channel noise estimate and scales the input signal and noise estimate based on a probability distribution parameter associated with PAS modulation.
* The receiving device demaps the modulation constellation of the input signal using the scaled input signal and noise estimate to provide bits associated with the PAS modulated constellation.
* The probability distribution parameter can be estimated at the receiving device or provided by the transmitting device.

==Original Abstract Submitted==

Methods, systems, and devices for wireless communications are described in which a receiving device, such as a base station or user equipment (UE), may receive an input signal that is modulated according to a probabilistic amplitude shaping (PAS) modulation technique. The receiving device may determine an associated channel noise estimate and may scale the input signal and the channel noise estimate based on a probability distribution parameter that is associated with the PAS modulation. The receiving device may demap the modulation constellation of the input signal based on the scaled input signal and the scaled channel noise estimate and provide one or more bits associated with the PAS modulated constellation. The probability distribution parameter may be estimated at the receiving device, or the transmitting device may provide the probability distribution parameter to the receiving device.
