APPARATUS, METHOD, AND COMPUTER PROGRAM PRODUCTS UTILIZING A GENERALIZED TURBO PRINCIPLE

摘要

Exemplary embodiments of the invention provide a generalized Turbo principle that enables the exchange of region beliefs between components. The generalized Turbo principle provides various advantages over the traditional Turbo principle such as, for example, a lower Bit Error Rate (BER) and/or a better quality of the end-result marginals. In one exemplary embodiment, a method includes: receiving an encoded signal (501); and decoding the received signal using a generalized Turbo principle wherein region beliefs are exchanged between components (502). In another exemplary embodiment, methods, computer programs and apparatus are presented for generating a graph structure for a system having a plurality of components. As a non-limiting example, the generated graph structure may be seen to correspond to the region graphs underlying the generalized Turbo principle.
