sequential design
Examples
- 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
