摘要： A method is provided for generating a multiple band ultrawide bandwidth signal. In this method, an ultrawide bandwidth devices provides a first reference signal having a first reference frequency, and a second reference signal having a second reference frequency that is different from the first reference frequency. The device generates a first ultrawide bandwidth signal based on the first reference signal, and a second ultrawide bandwidth signal based on the second reference signal, creating two separate frequency bands. These two signals can be generated form the same base clock signal, allowing for significantly simpler implementation and modification.

摘要： A method is provided for operating a wireless local device. In this method a local device receives a beacon for a current superframe in a common signal format. The beacon includes time slot assignment information. The local device then determines a device format for the transmission of data to a remote device based on format determination information. The device format can be one of a common signal format, and one or more wireless formats. The local device then determines one or more remote device time slots in the superframe assigned for transmission of the data to the remote device based on the time slot assignment information. Finally, the local device transmits the data in the one or more remote device time slots to the remote device using the device format.

摘要： A method is provided for transmitting data. A first device (121) generates a first signal (320) having a first duty cycle, comprising a first gated-on portion (323) and a first gated-off portion (363) in a time slot (260); and a second device (125) generates a second signal (330) having second duty cycle, comprising a second gated-on portion (333) and a second gated-off portion (363) in the same time slot (260). The first gated-on portion (323) is generated during a first segment of the time slot (260) and the first gated-off portion (363) is generated during a second segment of the time slot (260), while the second gated-on portion (333) is generated during the second segment and the second gated-off portion (363) is generated during the first segment.

摘要： A system and method are provided for authenticating a new device in a wireless network using an authentication device. First, the new device estimates the distance between the new device and the authenticating device as a first distance measurement, and sends the first distance measurement to the authentication device. The authentication device then estimates the distance between the new device and the authenticating device as a second distance measurement. The authentication device then evaluates the first and second distance measurements to determine if they meet authentication criteria and sends authentication data to the new device only if the first and second distance measurements meet the authentication criteria. These criteria can be that they do not differ by more than a set error value or that they both are below a set maximum value.

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 operating a wireless device. In this method, a first operation is performed on a wireless signal using a first group of wavelets arranged according to a first analog code word format (720). A second operation is then performed on the wireless signal using a second group of wavelets arranged according to a second analog code word format (740). The first code word format can be different in content and in size from the second code word format. By choosing different properties for each analog code word format, the device can optimize the performance of each operation. These operations can be performed in receiving process (800) or a transmission process (900).

摘要： The invention provides systems and methods that include, inter alia, wireless communication systems that integrate wireless receivers and transmitters with host computer platforms and that include a data access channel that delivers into the memory space of an application program digital data that is representative of a base band modulated signal. Accordingly, these systems can employ wideband digitization of an incoming signal, such as an RF signal, direct the digitized data into the application memory space of a general purpose workstation, and allow an application program operating on the general purpose work station to perform the digital signal processing that obtains the information encoded within the digitized signal.

A signal can be output with the waveform. A method of demodulating encoded data can include receiving a signal. Responsive thereto, data in the signal can be demodulated to reflect a position and phase of a waveform pulse. Responsive to the pulse and the phase, information represented by the data can be determined. A signal representative of the information can be output. A communication device for transmitting data can include a processor which, responsive to receipt of a datum, can determine a position and phase of a pulse in a waveform corresponding thereto.
