摘要:
提出了欧氏算法和IDFT相结合的RS码流式解码方案,并在FPGA芯片上予以实现。计算机仿真和实测表明,该方案在GF(28)的符号速率可达50MHz以上,最大延时为640ns,满足了高速宽带无线接入网中抗干扰编译码的需求。

Hardware Solution for RS Encoding and Decoding in Wide Band Wireless Access Networks
()
Abstract:
A streaming decoding method of RS code which is the seamless combination of Euclidean Algorithm and IDFT,is presented. This scheme has been realized in FPGA. The maximum symbol (GF(2~8)) rate and time delay are 50MHz and 640ns respectively.
