    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. Provided is an ultra low power wideband asynchronous BPSK demodulation circuit configured by comprising: 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 of which a cutoff frequency is a carrier frequency, so as to output an analog signal delayed by a ¼ period of the carrier frequency from an upper sideband analog signal, and a lower sideband analog signal; 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°, that is, an analog pulse signal indicated according to a phase shift part of a BPSK modulation signal, 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: 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.
