Recovering Data from Pdu Stream with HCS Error in WIMAX

摘要：

　　In IEEE 802.16e (WiMAX),each data burst consists of multiple MPDUs.The MPDUs of one data burst are distinguished from each other according to the generic MAC header (GMH).The GMH contains the length information of MPDU.If the GMH is damaged,it doesnt know whats end of the MPDU.As a result,the damaged MPDU and successive MPDUs in the data burst shall be discarded even if the successive MPDUs are correct received.In this paper,we point out the cursory discarding and propose a recovering scheme to improve the network bandwidth.
