Abstract

We think about the problem of reliable transmission of information over AWGN channels using rateless codes. We introduce a new family of rateless codes, named the accumulate rateless (AR) codes, which is easy to construct as traditional LT codes but has better performance and lower complexity. We investigate the performance of AR codes over AWGN channels, and simulation results are presented, showing that not only the error floor performance but also the waterfall performance are better than LT codes.
