Abstract
: The sum-product algorithm (belief/probability propagation) can be naturally mapped into analog transistor circuits. These circuits enable the construction of analog-VLSI decoders for turbo codes, low-density parity-check codes, and similar codes. Index Terms: Turbo codes, iterative decoding, factor graphs, belief propagation, analog circuits. The material in this paper was presented in part at the 1998 IEEE Int. Symp. on Information Theory, Cambridge, MA USA, August 16-21, 1998, and at several other conferences. This research was supported by the Swiss National Science Foundation under Grant 21-49619.96. 1 Now with Signal and Information Processing Lab (ISI), ETH Zentrum, CH-8092 Zrich, Switzerland. The work was performed while with Endora Tech AG, Basel. 2 Signal and Information Processing Lab (ISI), ETH Zentrum, CH-8092 Zrich, Switzerland. 3 Now with Globespan Semiconductor Inc., 100 Schulz Drive, Red Bank, NJ 07701.
