EKA扩展译码算法优化及其DSP实现研究

EKA Extended Decoding Algorithm Optimization and Its DSP Realization

软件无线电接收机对实时性的要求很高,必须选择执行速度较快而又节省存储空间的译码方式。介绍了格雷码的扩展译码算法(EKA)[1],并与其他算法进行了比较。提出了扩展格雷码的译码方案,在基于DSP的软件无线电接收机中实现了EKA算法并进行了优化。通过实验结果和实际应用可知,EKA算法的执行效率优于文中介绍的其他算法,并可以实现扩展格雷码的实时译码。

In this paper, we present an EKA extended decoding algorithm and compare it with other algorithm. Then we introduce extended Golay code decoding algorithm. According to experiment results, it indicates that the efficiency of EKA extended decoding algorithm is better than other algorithm described in this paper, and EKA extended decoding algorithm can also carry out extended Golay code decoding algorithm. This is very important in engineering.
