Benchmarking of learning architectures for digital predistortion
2016 50th Asilomar Conference on Signals, Systems and Computers, 2016 Indirect and direct learning architectures are the two main parameter identification approaches for digital predistortion systems. While the indirect scheme is less complex, its inherent shortcomings are avoided by the direct learning approach. Trying to

Programmable photonic unitary circuits for light computing. [PDF]
NanophotonicsAbstract Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary operations on light waves in a universal and programmable manner enables the emulation of complex light–matter interactions and the execution of general‐purpose ...

Performance of digital predistorter in system with analogue to digital converter
IET Communications, 2022 Abstract The baseband digital pre‐distortion (DPD) signal processing technique is the most cost‐effective linearisation method among other techniques to address the nonlinearity effect of the power amplifier. For communication systems containing DPD and power amplifier, it is difficult to acquire performance metrics closed‐forms for ...
