一种适用于CCSDS规范的数据交织与解交织方法设计

A kind of applicable to CCSDS standard data interleave and de-interleave method

数据的交织与解交织通常与信道编译码器结合使用,组成信道纠错系统。此类系统可将突发错误离散成随机错误,使突发错误散布在译码器纠错范围之内,提高信道抗干扰能力。本文针对CCSDS规范中RS编译码的特点,设计了一种数据交织与解交织的方法。该方法根据不同的交织深度,对数据进行分类处理。实现了不同交织深度下数据的交织与解交织。同时在FPGA中对此方法进行了设计和仿真。仿真结果表明该方法可实现适用于RS编译码的数据交织与解交织功能。

Data interleave and de-interleave is usually combined with channel decoder, error correction system of channel. In the systems,burst er- ror can be divided into random errors.The burst error spread within the scope of the decoder error correction.Channel anti-interference ability was improved.In this paper, according to the characteristics of RS coder in the CCSDS standard compiler design a kind of data interleave and de-interleave method.The method classify data processing according to the different interleave depth.Implements the interweave and de-interleave of data in different interleave depth.This method is simulated and implemented in FPGA.The results show that the method can realize the function of data interleave and de-interleave based on RS decoder.
