摘要： 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.

A first device generates a first signal having a first duty cycle, comprising a first gated-on portion and a first gated-off portion in a time slot; and a second device generates a second signal having second duty cycle, comprising a second gated-on portion and a second gated-off portion in the same time slot. The first gated-on portion is generated during a first segment of the time slot and the first gated-off portion is generated during a second segment of the time slot, while the second gated-on portion is generated during the second segment and the second gated-off portion is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots and provide error correction, power control, and the like.

摘要： A method (500) is provided for operating an interleaver circuit 120 having N shift lines (2201-220N). Each shift line has a line input node, a line output node, and one or more bit storage elements (240). The method includes: storing don't-care bits in each bit storage element (520); isolating the line output nodes from an interleaver output node (520); receiving a stream of data bits at an interleaver input node (530); and sequentially connecting the interleaver input node to respective line input nodes to shift the stream of data bits into the bit storage elements of corresponding shift lines in an interleaved fashion (530). A don't-care bit is shifted out of each of the bit storage elements in corresponding shift lines as each data bit is shifted in. A last don't-care bit is shifted out of respective bit storage elements in the shift lines during N consecutively-received data bits.

摘要： A method is provided for performing a clear channel assessment in a local device. The local device receives signal energy in a wireless channel and splits the received signal energy into a real portion and an imaginary portion. It determines a real portion of a squared signal energy by subtracting a squared imaginary portion of the signal energy from a squared real portion of the signal energy, and determines an imaginary portion of the squared signal energy by calculating twice the product of the real and imaginary portions of the signal energy. It can perform a signal detection function on the real and imaginary portions of the squared signal energy to produce a clear channel assessment signal that indicates whether a set signal type is present in the wireless channel. This clear channel assessment signal can be used to determine whether the local device should remain in a low-power mode.
