Abstract

In a cell-based transmission protocol such as ATM, a Cyclic Redundancy Check code is used for error detection at a frame level, and a Hamming code is used for error correction at the cell level, to improve error protection, and reduce the need for retransmission. The method can be used as a modification to ATM Adaption Layers.
