Superimposed codes based on punctured convolutional codes

M. Hattori, Yuichi Saitoh

Abstract

Punctured convolutional codes of rates k1/n and k2/n are applied to |u|u + v| construction, and then a superimposed code of rate (k1 + k2)/(2n) is constructed. A suboptimal decoding procedure is presented for the superimposed codes, and it reduces the decoding complexity as compared with maximum likelihood decoding for the known convolutional codes.
