Abstract: Techniques are described for peak-adaptive sampling demodulation for radiofrequency transceivers. For example, a tag input signal is received via an antenna, from which a clock input signal can be extracted. Multiple clock output signals can be generated responsive to the extracted clock input signal, such that each has a different respective phase. A multiphase selector can identify the one of the clock output signals that has the respective phase that is closest to the phase of the tag input signal and is best suited for sampling the peak of the tag input signal, accordingly. A single-path detector can generate a data output signal by using the identified clock output signal to sample the tag input signal, and the detector can filter and amplify the data output signal using small-signal devices.

Faces or other features of interest can be detected in the fused image and identified in a library.

Abstract: Data compression using a memristive crossbar is enabled. Conductances of memristors may be set such that the memristors of the crossbar act as coefficients of a wavelet transformation coefficient matrix with respect to voltage signals applied to input rows of the crossbar. The memristors may act as coefficients of the transpose of the wavelet transformation coefficient matrix when voltage signals are applied to input columns of the crossbar. Hence, the memristive crossbar may be used to implement a two dimensional (2D) discrete wavelet transform (DWT) on two dimensional data (e.g., image data) encoded in the voltage signals. The resulting currents in the columns of the memristive crossbar may be integrated and converted to voltage signals that are fed back into columns of the memristive crossbar such that the rows of the memristive crossbar output electronic signals that correspond to the image data compressed in accordance with Haar 2D-DWT image compression.

Abstract: Aspects of the present disclosure provide techniques for using cyclic-shifts in code division multiplexing to shift transmitted signals (e.g., reference signals, control signals, and/or data) from different antenna ports of the transmitting device. Particularly, for multiple-input multiple-output (MIMO) systems that multiply the capacity of a radio link by using multiple transmit and receive antennas to exploit multipath propagation, aspects of the present disclosure minimize interference at the receiving device by separating the signals from different antenna ports based on the channel impulse response (or delay spread) of each antenna port of the channel. In some examples, the transmitting device may maximize resource utilization by interleaving the reference signals, control signals, and/or data from a plurality of antenna ports while maintaining adequate spacing between each signal.
