Constrained interleaved coded modulation technique known to map coded bits of outer block codes onto a higher‐order constellation is extended with suitable adjustments for outer convolutional codes. A novel puncturing technique based on the mapping is proposed to generate powerful punctured coded schemes. It is demonstrated that the proposed mapping and puncturing techniques are significantly better than their traditional counterparts.
