Block Markov superposition transmission (BMST) of first‐order Reed–Muller and extended Hamming (RMEH) codes is investigated. Multiple code rates can be easily realised by adjusting the mixture ratio of Reed–Muller and extended Hamming codes. Compared with the original BMST of repetition and single‐parity‐check (RSPC) codes, the proposed BMST‐RMEH codes can perform close to Shannon limits over a wide range of code rates with about only half the encoding memories of BMST‐RSPC codes. As a result of the reduction of encoding memories, the decoding complexity and delay of BMST‐RMEH codes are approximately half (or even lower than) those of BMST‐RSPC codes.
