Generic FG-SPA update rules design of linear canonical message representation
Original language description
This paper focuses an implementing issue of the sum-product algorithm on factor graphs (FGSPA) in a general system. The overall goal is to propose a message representation and corresponding update rules for both discretely and continuously valued variables with an acceptable exactness-complexity trade-off. We propose the update rules for a generic class of linear message representations with orthogonal canonical kernels. The proposed update rule design is combined with an already known message parameterization based on the Karhunen-Loeve Transform (KLT) of the message. This combination of the proposed generic update rules with the KLT-message representation forms a generic implementation framework of the FG-SPA applicable whenever the KLT is defined. This framework preserves the properties of the KLTmessage representation that is the best linear approximation in the MSE sense. A particular example on a joint detection and phase estimation is shown to verify the framework and to compare
