Abstract: Disclosed is a channel-dependent multi-carrier code division multiple access (MC-CDMA) technique with adaptive spreading codes. Adaptive spreading codes are used for each subcarrier per user which increase the security level of conventional MC-CDMA. Two different map designs are proposed: fixed and adaptive interval maps. These maps are shared among all nodes and gives information about the spreading code sequences for corresponding channel gains.

Abstract: Disclosed is a method for allocating resources for the low power backscatter devices in a sparse environment with a beamspace channel model in a symbiotic radio system.

Abstract: Three-dimensional (3D) printing is implemented to introduce randomness into systems and devices that are being manufactured. 3D printed physically unclonable wireless systems (PUWS) provide flexibility in system package complexity, number of physically unclonable function (PUF) based security measures/types, and customization of the PUF parameters. Using flexibility and economics of 3D printing, PUWS can combine multiple PUF measures in a 3D package for cryptographic secret keys and introduce PUFs at the physical layer of the communication system. A 3D printed wireless system packaging concept is described herein where 3D printing parameters are randomized to 1) generate new physically unclonable functions (at the physical layer), 2) generate new physically unclonable functions within the system package (rather than at integrated circuit (IC) level), and 3) combine multiple physically unclonable functions (such as optical and electrical/VIA based ones) within single device structure.

Abstract: Some embodiments in the present disclosure relate to sensing application identification. For example, a wireless signal is obtained to be further processed. Then, presence of a sensing signal in the received signal is estimated, the sensing signal being a signal generated by a sensing application. Based on the estimation of the sensing signal, wireless reception, transmission or sensing is then performed. The sensing application detection and/or identification may be performed by a trained model such as machine learning based model. The wireless reception, transmission or sensing performed according to the result of the estimation may further include channel access, resource allocation, utilization of the detected sensing signal for own sensing purposes, or the like.
