TL;DR: This article formulates the monostatic radar system model starting from the communication system model and shows the accuracy of the proposed system to measure the velocity of mobile objects at various speeds while the device is simultaneously served as a node to perform in-band bidirectional communication.

TL;DR: A novel nonlinear digital self-interference canceller algorithm based on an augmented Hammerstein model, its implementation details on a software-defined radio (SDR) platform, and performance results of real-time full-duplex experiments on both device and link level are presented.

TL;DR: A high data rate implementation of a digital predistortion (DPD) algorithm on a modern mobile multicore CPU containing an on-chip GPU that is capable of running in real-time, and combined with the low complexity DPD design allows for more than 400 Msamples/s sample rates.

TL;DR: Results show that efficient mmW array linearization can be obtained through the proposed methods at very low complexity, and the processing and learning complexities of the considered techniques are analyzed, which allows to assess the complexity–performance tradeoffs of the proposed solutions.

TL;DR: RF measurements conducted with real-life equipment indicate favorable PIM suppression levels of up to 20 dB using both introduced techniques, and an alternative canceller solution with a reduced number of BFs is proposed, inspired by the problem modeling.
