Self-demodulation of high-frequency ultrasound

The Journal of the Acoustical Society of America, 2010
High-frequency (>10 MHz) ultrasound is used in, e.g., small animal imaging or intravascular applications. Currently available ultrasound contrast agents (UCAs) have a suboptimal response for high frequencies. This study therefore investigates the nonlinear propagation effects in a high-frequency ultrasound field (25 MHz) and its use for standard

Ionospheric self-demodulation and self-distortion of radio waves

Journal of Atmospheric and Solar-Terrestrial Physics, 1959
Abstract Experiments in which the phenomenon of ionospheric self-demodulation was investigated are described. Demodulation is observed to occur only at the lower modulation frequencies, and it is concluded that the occurrence of the phenomenon can be satisfactorily explained by an extension of Bailey 's theory of ionospheric cross-modulation as ...

An information theoretical analysis of self-demodulating waveform channels

2017 International Symposium on Wireless Communication Systems (ISWCS), 2017
This paper studies nonlinear waveform channels which show a self-demodulating characteristic from an information theoretic point of view. These channels contain in the most simple case a square-law nonlinearity followed by a lowpass filter. In this paper, the use of orthonormal series expansions based on sets of sampling functions is discussed for both

A 60GHz BiCMOS self-demodulator with injection locked oscillator

2011 International SoC Design Conference, 2011
This paper proposes a wide-band self-demodulating receiver for 60GHz ISM band applications. The proposed receiver architecture self-demodulates the OOK input signal by using injection locked oscillator and passive mixer. This simple architecture features extremely ultra-lower-power consumption and faster settling time.
