Abstract A new polar-coded modulation (PCM) framework with the bit interleaving is proposed to enhance the polarization diversity among the bit polarized subchannels under the finite block length, consequently, the transmission reliability is further improved. The key idea is asynchronously transmitting the coded bits within one block and spatially coupling multiple coded blocks by the joint modulation, and the polarization diversity among the modulation synthesized subchannels under the parallel partition is enhanced. Combining the binary polar coding, this polarization enhancement at the modulation partition stage is then delivered to the final bit polarized subchannels. The capacity-achieving property under the infinite block length and the polarization superiority with respect to state-of-the-art PCM schemes under the finite block length are proved. Finally, the simulation results indicate the performance gain compared to the conventional PCM and 5G LDPC coded modulation schemes.
