Abstract
Disclosed herein are a method, an apparatus, and a carrier medium including one or more computer readable code segments to instruct one or more processors of a processing system to implement a method. The method is in a first wireless station of a wireless network. The method comprises generating a check sequence to protect the integrity of a subpacket of a packet, wherein the packet is to be wirelessly transmitted. The method further comprises embedding the check sequence in an embedding field within the packet. The embedding field is located prior to the end of the subpacket. The method further comprises wirelessly transmitting the packet. The check sequence is generated such that a second wireless station wirelessly receiving a signal corresponding to the packet can sequentially verify the integrity of the subpacket as if the check sequence were appended at the end of the subpacket being protected.
