Abstract: An artificial intelligence eye disease screening and diagnostic system based on an ophthalmic robot, comprising a human eye positioning analysis module, an image information collection module, an AI picture quality monitoring module, an eye disease analysis and diagnosis module, a data storage management module, and an execution control module. The system can replace ophthalmologists to perform eye disease diagnosis tasks in regions lacking ophthalmologists, and assists the ophthalmologists in eye disease screening and diagnosis in large hospitals with a large number of patients, thus improving diagnosis efficiency.

Abstract: A method for performing transmission and reception of signals in a radio transceiver arrangement includes creating a first analogue signal to be transmitted based on a digitally predistorted digital input signal and converting a second analogue signal into a digital output signal. The second analogue signal is a combination of a received signal and a transmitter observation signal. The received signal is based on a radio signal received by the radio transceiver arrangement. The transmitter observation signal is based on a tapped signal of the first analogue signal. The digital predistortion of the digital input signal is adapted based on the part of the output digital signal that corresponds to the transmitter observation signal.
