1. A method for detecting a received signal comprising:
- determining a set of particles each modeling a potential signal generated by a transmitter;
measuring a received signal from the transmitter;
calculating a probability for each of the particles, the probability for a particle indicating likelihood of the potential signal modeled by the particle based upon the received signal;
redistributing the particles within a space of potential signals that may be generated by the transmitter based upon the probabilities;
selecting one of the particles based upon the distribution of the particles within the space of potential signals; and
outputting the potential signal modeled by the selected particle.

Abstract
A receiver uses probabilistic techniques to identify the value of a received signal based upon a space of potential signals that may be generated by the transmitter. The receiver uses one or more iterations in which received signal values are compared with potential signal models to enable identification of the incoming signal.
