Song Yi-mei, Jianyong Zhang, Weiguo Hu, Fengju Fan · 2021
In order to improve the performance of bit-interleaved polar coded MIMO systems (BI-PC-MIMO), we propose two optimized interleavers for BI-PC-MIMO with parallel antenna partition. One of the schemes is the generalized method of compound interleaver and the other one flips the bits twice before mapping them to the symbols with modulation scheme. The simulation results show that the proposed interleaving schemes can outperform the random interleaver with 0. 25dB for 16QAM in some certain configurations.
