Abstract: A method and an apparatus for identifying transmitting radio devices from a plurality of radio deviceswithin a video feed is described. At least one radio signal identifying a transmitting radio device is received, from the plurality of radio devices. A video feed identifying radio deviceswithin a field of view of the computer vision (CV)system is received, from the CV system. A first set of features is extracted from the received at least one radio signal and a second set of features is extracted from the received video feed. The first set of features and the second set of features are provided as an input to a machine learning (ML) algorithm to obtain a relationship between the transmitting radio device and the radio devicesidentified in the video feed.

Abstract: An apparatus, method and computer program performs initializing parameters of a transmission system. The transmission system comprises a transmitter, a first channel, a relay, a second channel and a receiver. The transmitter includes a transmitter algorithm having trainable weights, the relay includes a relay algorithm having trainable weights and the receiver includes a receiver algorithm having trainable weights. A first training sequence of messages is received, and the first training sequence of messages is sent from the transmitter to the relay using the first channel and is sent from the relay to the receiver using the second channel. A loss function is obtained or generated, and trainable parameters of the transmission system are updated based on the loss function. The trainable parameters include some of the trainable weights of the transmitter, some of the trainable weights of the relay, and some of the trainable weights of the receiver.

Abstract: A communication system including at least one receiver and at least one transmitter is described. The receiver is configured to communicate with the transmitter using a plurality of resource elements within a time-frequency OFDM grid. The transmitter is configured to transmit data-carrying symbols using all resource elements of the plurality of resource elements within the OFDM grid, wherein the data-carrying symbols are modulated using a constellation C. The receiver is configured to receive the data-carrying symbols on all resource elements of the plurality of resource elements within the OFDM grid, and to implement a neural network, configured to operate jointly on the plurality of resource elements, and to output, based on the received data-carrying symbols, a plurality of LLRs to reconstruct information bits from the received data-carrying symbols. The neural network is optimized with respect to the constellation C.
