Simplified Explanation
This abstract describes a method for demapping a signal to a specific point in a signal constellation. The method involves identifying a seed point in the signal constellation from a received signal. A candidate set of codes is then generated based on the seed point and a perturbation applied to it. A probability distribution is created over the candidate set of codes, and a point in the signal constellation corresponding to the received signal is identified based on this distribution. The identified point is the code in the candidate set with the highest probability, and it is output as the value of the received signal.
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques and apparatus for demapping a signal to a point in a signal constellation. An example method generally includes identifying a seed point in a signal constellation from a received signal. A candidate set of codes for the signal is generated based on a seed point and an additive perturbation applied to the seed point. A point in the signal constellation corresponding to the value of the received signal is identified based on a probability distribution generated over the candidate set of codes. Generally, the identified point corresponds to a code in the candidate set of codes having a highest probability in the probability distribution. The point in the signal constellation is output as the value of the received signal.
