This paper introduces the construction of systematic regular RA codes and makes a brief analysis of the bound of the systematic regular rate-1/2 RA codes for binary erasure channels. The asymptotical performance of such codes is given and the union bound is simulated. The analytical and simulation results show that the structure of the regular RA code plays a great role in the performance of the code.
