System and method for passing data frames in a wireless network
First Claim
1. A method of receiving a data frame in an ultrawide bandwidth network, comprising:
- receiving an ultrawide bandwidth signal containing a data frame;
performing an acquisition operation during a first preamble in the data frame;
identifying a marker after the first preamble that indicates that the first preamble has ended;
performing a signal processing operation during a second preamble in the data frame, after identifying the marker;
receiving a header in the data frame, after performing signal training; and
receiving a payload in the data frame, after receiving the header.

Abstract
A method is provided for receiving a data frame in an ultrawide bandwidth network. In this method, a device receives an ultrawide bandwidth signal containing a data frame. The device then performs an acquisition operation during a first preamble in the data frame, and identifies a marker after the first preamble that indicates that the first preamble has ended. After this, the device performs a signal processing operation during a second preamble in the data frame. After the training, the device then receives a header in the data frame, and then receives a payload in the data frame. By having a marker between the two preambles, this method provides a receiving device with critical information regarding the timing of the preamble section of a frame.

14. 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. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
