Inner coding consists of punctured-convolution coding, bitinterleaving and symbol interleaving.
内层包括删余卷积编码、位交织和符号交织。

After have discussing the low-bitinterleaving and skewed interleaving address technologies we presented address scheme of KD-VIM-1. We have implemented embedded memory system of KD-VIM-1 in VHDL.
The results of simulation show that RS coding and interleaving are fit for the channel of space laser communication, and can largely decrease bit error rate(BER).
