Abstract: We consider Plotkin-type constructions that perform a multi-step recursive decomposition of a given code into the shorter codes and are similar to polar and Reed-Muller (RM) codes. However, we end this decomposition process at the various short codes instead of the single information bits used as end nodes in polar design. We also employ maximum likelihood (ML) decoding of the end codes. Such a design can reduce the output error rates of polarised constructions on the moderate blocklengths. We also analyse the complexity-performance trade-offs in order to optimise code design.
