Soft Decision Decoding of Block Codes

Abstract

An open problem in communications is the construction and decoding os asymptotically good block codes - those which drive the probability or error to zero while bounding the code rate form below as the block length becomes infinite. The author's Improved Iterated Codes have these properties, but larger rate bounds and simpler decoding would be useful. Soft decision decoding promises some of each. This report reviews soft decision techniques from simple eraser reconstruction through generalized minimum distance decoding and its extensions. Those which seem most suited for Improved Iterated Codes are identified. Author.
