Abstract :
In this paper we present an analog implementation of the mean-field algorithm for inference in undirected graphical models (UGM). One of its numerous applications is signal detection in wireless receivers which can benefit from low power analog circuitry. An example detector for a double Alamouti space-time block code (STBC) has been designed and laid out in a 0.25mum SiGe BiCMOS process.
