Abstract: 
The Hybrid Fiber-Coax (HFC) network is being paid close attention to in recent years as a bi-directional broadband access network.To achieve seamless connection with the backbone network,an Asynchronous Transfer Mode (ATM) Network Network Interface (NNI) cell format is used as the basic transmission packet unit in the HFC system. As the transmission condition of the HFC system's upstream channel is bad, two improved header error control (HEC) schemes, i.e. the improved HEC and the cell Interleaving Technique,are employed to guarantee the packet integrity. Theoretical analysis of the results showed that the improved HEC and the cell Interleaving Technique are applicable to isolated random errors and burst errors, respectively.
