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: To support a wide range of code rates in probabilistic shaping based modulation schemes solutions, a constellation which is at least based on a trained model is used in the modulation. Depending on an implementation the trained model may be a constellation comprising a plurality of sub-constellations with trained parameters as constellation points, or the trained model may be for generating a constellation and corresponding constellation points.

Abstract: A method, apparatus, receiver and system provide timing synchronization during data transmission over a channel. In the context of a method, the method receives, for individual ones of a plurality of sequences of samples generated by a channel in response to transmission of corresponding frames that are comprised of a plurality of symbols including a preamble and one or more data symbols: (i) a probability vector and (ii) an indication of the sample of the respective sequence that corresponds to the particular symbol of the corresponding frame. The method determines one or more updated parameters of a frame detector of a receiver that receives the sequence of samples from the channel. The method determines one or more updated parameters of a preamble generator of a transmitter that provides the preamble for transmission over the channel.

Abstract: In a communication system, a transmitter includes a transmit filter for pulse shaping to produce a transmit signal subject to a signal constraint for transmission over a channel to a receiver, and the receiver includes a receive filter to process a received signal. The transmit and receive filters are implemented through a filtering function with trainable parameters, the parameters obtained by joint optimization of the transmit and receive filters to maximize the transmission rate for the channel model and the signal constraint. The learning method for obtaining the parameters includes: simulating the channel response depending on the transmit and receive filters, simulating a channel noise correlation depending on the receive filter, computing channel outputs for random samples by applying the simulated channel response and a random noise correlated to reflect the simulated channel noise correlation, learning the parameters by minimizing a loss function subject to at least one signal constraint.
