Abstract: An embodiment of the present invention relates to an ultra low power wideband asynchronous binary phase shift keying (BPSK) demodulation method and a circuit configuration thereof. The ultra low power wideband asynchronous BPSK demodulation circuit comprises a sideband division and upper sideband signal delay unit dividing a modulated signal into an upper sideband and a lower sideband by a first order high-pass filter and a first order low-pass filter; a data demodulation unit latching, through a hysteresis circuit, a signal generated by a difference between the analog signals in which a phase difference between the delayed upper sideband analog signal and the lower sideband analog signal is aligned at 0°, so as to demodulate digital data; and a data clock recovery unit for generating a data clock by using a signal digitalized from the lower sideband analog signal through a comparator and a data signal.

Abstract: An ultra-wideband (UWB) communications system combines the techniques of a transmitted reference (TR) and a multiple access scheme called delay hopping (DH). Combining these two techniques using UWB signaling results in a penalty in signal-to-noise ratio (SNR) over conventional pulse position modulation (PPM) techniques but avoids the synchronization difficulties associated with conventional approaches. The signaling pulse waveforms are designed to insure that their power spectral densities, after any frequency translation to the center of an operating band, are essentially spectrally disjoint with frequencies that must be protected. This TR technique is combined with the DH multiple access technique to create a UWB communications scheme that has a greater multiple access capacity than does the UWB TR technique by itself.

Abstract: A multiple access technique for a wireless communication system establishes separate channels by defining different time intervals for different channels. In a transmitted reference system different delay periods may be defined between transmitted reference pulses and associated data pulses for different channels. In addition, a multiple access technique may employ a common reference pulse for multiple channels in a transmitted reference system. Another multiple access technique assigns different pulse repetition periods to different channels. One or more of these techniques may be employed in an ultra-wide band system.

The mixer mixes the operting signal with another signal to generate a transmission signal. An RF receiver includes a first mixer, a second mixer, an integrator/sampler, and a signal generator. The first mixer receives as its inputs an input RF signal and a second input signal, and mixes its input signals to genrate a mixed signal. The integrator/sampler receives the mixed signal and processes it to provde an output signal. The integrator/sampler receives the mixed signal and processes it to provide an output signal. The signal generator provides an operating signal in response to a selection signal. The operating signal has a frequency equal to the frequency of a reference signal, multiplied by a number.
