  1. The principles of erasure codes used under binary erasure channels are summarized and erasure codes which belong to standard classes of rs codes are introduced with emphasis on cascaded low - density erasure codes with linear time encoding and erasure recover algorithms. thresholds of regular degree distributions are analyzed. it is shown that low - density erasure codes based on ( d, 2d ) - regular sequences of degree distribution are not close to optimal ( d 3 ). two pares of irregular degree distribution sequences are introduced and a pare of improved right regular sequences of low - density erasure codes are presented, it is testified that the new sequences are asymptotically quasi - optimal. in the meantime, simulations of cascaded low - density erasure codes based on a few types of special sequences of degree distribution available are given, together with performance analyses on these codes
