Abstract: Examples of active millimeter-wave imaging systems are described which may utilize modulation schemes to provide illumination signals. The use of modulation techniques may allow for the use of direct-conversion receivers while retaining an ability to separate desired received signal from self-jamming and/or DC offset signal(s) generated by the direct-conversion receivers. In some examples, modulation schemes include the use of balanced orthogonal codes which may support MIMO or massive MIMO imaging systems.

Abstract: Examples described herein utilize a backscatter signal provided by a wirelessly powered device to estimate channel information, (e.g., a channel transfer function) between the wirelessly powered device and a transmitter system. The channel information may be used to optimize MIMO power transfer for linear as well as nonlinear backscatter devices. Examples of die method ‘may shift some or all of the power cost and complexity of coherent channel measurements from the WFD to the transmitters), and allow WPT optimization to milliwatt- or microwatt-class wirelessly powered devices.
