| Abstract: | The interleaver is an influential factor for the anti-decline ability of bit-interlveaved coded modulation （BICM）in free space optical communication （ FSO ）. After the FSO BICM communication system model is introduced, the design rules of interleaver and its mathematical expressions are given, the distance property of Pseudo-random interleaver, S-random interleaver and imporved golden interleaver, as well as their performance under weak turbulence are analyzed by simulations. The results show that the interleaver can improve the performance of coded modulation efficiently, the given interleave pattern and added interleaving length further, and the interleaver based on characteristic design can provide better performance in some interleaving length. |
| Keywords: | optical communication coded modulation inteleaver distance property error performance |
