System and method for passing data frames in a wireless network

A method of sending a data frame in an ultrawide bandwidth network, comprising:

• sending a first preamble, the first preamble comprising a first pseudo-random sequence;
• sending a marker after the first preamble that indicates that the first preamble has ended, the marker comprising a known plurality of bits;
• sending a second preamble in the data frame after the marker, the second preamble comprising a second pseudo-random sequence;
• sending a header after the second preamble;
• and
• sending a payload after receiving the header.

A receiver in an ultrawide bandwidth network, comprising:

• a code processor configured to receive an ultrawide bandwidth signal containing a data frame;
• an acquisition detector configured to perform an acquisition operation during a first preamble in the data frame;
• a marker detector configured to identify a marker after the first preamble that indicates that the first preamble has ended;
• a decision feedback equalizer circuit configured to perform a receiver training operation during a second preamble in the data frame, after identifying the marker.
