Abstract: We present two sequences of ensembles of nonsystematic irregular repeataccumulate codes which asymptotically (as their block length tends to infinity) achieve capacity on the binary erasure channel (BEC) with bounded complexity. This is in contrast to all previous constructions of capacityachieving sequences of ensembles whose complexity grows at least like the log of the inverse of the gap to capacity. The new bounded complexity result is achieved by allowing a sufficient number of state nodes in the Tanner graph representing the codes. ©2004 IEEE.
