We introduce a family of rateless codes, namely the doped accumulate LT (DALT) codes, that are capacityapproaching on a binary erasure channel (BEC) with bounded encoding and decoding complexity. DALT codes can be either systematic or non-systematic. Non-systematic DALT codes are very similar to raptor codes, except that joint optimization on the full coding graph can be applied to DALT codes, and thus they can be optimized to have better asymptotic performance than raptor codes. Systematic
