Abstract
A technique detects the presence of a packet identification sequence in a received sequence of samples received over a communications network. The packet identification sequence, when present and properly detected in a received packet, is used to determine a particular type of the received packet from a plurality of packet types that may be received over the communications network. The technique for detecting the packet identification sequence includes detecting a null sequence in the received packet and a predetermined identification sequence in the packet. Detection of the predetermined sequence uses energy estimates for corresponding windows of received samples.
