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.

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 mono-cycle generating circuit includes a multiplexer, a pulse generating circuit, and a buffer circuit. The multiplexer receives data of a logical 1 or a logical 0, determines whether to generate a positive mono-cycle or a negative mono-cycle, based upon the data, and outputs clock signals varying in time based upon the data. The pulse generating circuit is coupled to the multiplexer, receives the clock signals and generates a first series of pulses including an up-pulse preceding a down-pulse, or a second series of pulses including a down-pulse preceding an up-pulse, in response to the clock signals received by the multiplexer. The buffer circuit is coupled to the pulse generating circuit and includes a switch circuit and a common mode buffer. The switch circuit generates the positive mono-cycle or the negative mono-cycle, based upon whether the first series of pulses is received from the pulse generating circuit or the second series of pulses is received from the pulse generating circuit. The common mode buffer circuit is coupled to the switching circuit and reduces noise generated by the switch circuit.

摘要： A method apparatus are provided for mitigating spectral lines in a wireless signal. First a code word is generated that is made up of a plurality of binary or ternary encoded pulses. Then a plurality of code-word-modulated wavelets are generated in response to the code word. These wavelets can be Gaussian monopulses, repeated cycles of a sine wave, or other shaped impulse signals. The plurality of code-word-modulated wavelets are then modulated with a bit of transmit data to form a plurality of data-modulated wavelets. This modulation serves to whiten the signals since the transmit data is effectively random. Finally, the plurality of data-modulated wavelets are transmitted to a remote device.

摘要： An ultra-wide band (UWB) waveform generator and encoder for use in a UWB digital communication system. The UWB waveform is made up of a sequence of shaped wavelets. The waveform generator produces multi-amplitude, multi-phase wavelets that are time-constrained, zero mean, and can be orthogonal in phase, yet still have a −10 dB power spectral bandwidth that is larger than the frequency of the peak of the power spectrum In one embodiment, the wavelets are bi-phase wavelets. The encoder multiplies each data bit by an n-bit identifying code, (e.g., a user code), resulting in a group of wavelets corresponding to each data bit. The identifying codeword is passed onto the UWB waveform generator for generation of a UWB waveform that can be transmitted via an antenna.

摘要： A receiver correlator structure for an ultra wide bandwidth communication system includes an antenna, a mixer, a bandpass filter, and a convertor. The receiver receives, via the antenna, an ultra wide bandwidth signal comprising a sequence of wavelets of particular shapes and positions, and transmits the received ultra wide bandwidth signal to the mixer. The mixer also receives and mixes with the received ultra wide bandwidth signal a local ultra wide bandwidth signal comprising a sequence of wavelets of particular shapes and positions correlated to the received ultra wide bandwidth signal. The bandpass filter removes the DC components from the mixed signal, and provides the resultant signal to the convertor. The receiver structure eliminates the local ultra wide bandwidth signal AC bias and DC bias terms and 1/f noise, yet detects long sequences of logical 1's and 0's, and allows operation with reduced bandwidth convertors.
