摘　　要：针对E-Band通信系统中高速数据传输对纠错码的要求,设计了并行高速RS编译码器。通过DAA算法优化脉动阵列编码器结构,采用共用DCME算法中的解关键方程方案减少加法器等单元数目,优化后的译码时延只有传统ME算法的20%。仿真结果表明,优化后的RS(255,239)编译码方案具有实现简单、复杂度低、纠错性能优异等特点,满足系统高速率性能需求。In order to meet the requirement of high-speed data transmission error correction code in E-band communication system, we designed parallel high-speed structures of RS encoder and decoder. The design used DAA algorithm to optimize systolic array and DCME algorithm to reduce the number of adders in key equation solution. Comparing with the traditional ME algorithm, the time delay of the optimized decoder reduced to 20%. Simulation results show that the optimized RS （255,239） encoding and decoding scheme meets the requirements of high-rate system with a simple, low complexity, excellent error correction performance.
