Abstract

Punctured convolutional codes of rates k/sub 1//n and k/sub 2//n are applied to mod u mod u+v construction, and then a superimposed code of rate (k/sub 1/+k/sub 2/)/(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.
