This paper introduces the construction of systematic irregular RA codes. The encoding line is used to describe the graph structure of IRA codes. Two interleaving strategies for IRA codes are analyzed and it is shown that the two interleaving strategies are equal. The rateless character of IRA codes is also shown. The performances of IRA codes with different rate in binary erasure channel are simulated. Simulation results show that the IRA codes is capacity achieving. The error floor performance of IRA codes is analyzed and the modified encoding method is presented to lower the error floor.
