Abstract: A computer-implemented method for generating training data for training an algorithm for estimating positioning variances in an imaging apparatus of an x-ray imaging system is provided. The method includes predetermining target positioning data for the imaging apparatus and calculating faulty positioning data, wherein the faulty positioning data deviates from the target positioning data by at least one predetermined positioning variance. An imaging method is simulated, in order to generate two or more simulated x-ray recordings, wherein a positioning of the imaging apparatus is simulated in accordance with the faulty positioning data. An annotated training data record is generated and stored, wherein the training data record contains two or more simulated x-ray recordings and at least one positioning variance as an annotation of the two or more simulated x-ray recordings.

Abstract: Encoders and decoders for encoding and decoding data according to a coding scheme. The encoder converts N bits of input data into M voltage signals for transmission over M parallel wires to a decoder having one or two decoding stages that recover the N bits of data from the M voltage signals. The coding scheme is an N-bit, M-wire PAM-Q code in which each voltage signal wi has one of Q voltage levels l1-lQ, where l1<l2< . . . <lQ, and the different sets of M voltage signals for the different N-bit input values are permutations of a single set of M voltage signals. The decoder has a comparator stage. For the decoder having one other decoding stage, the other decoding stage is a computation stage or a logic stage that is before or after the comparator stage.

Abstract: A method is provided for channel estimation of an antenna array comprising multiple antenna elements. The method comprises obtaining channel state information for antenna elements with a high-end radio frequency chain, wherein the antenna elements with the high-end radio frequency chain are placed in the antenna array intermittently with antenna elements with a low-cost radio frequency chain. Channel state information is estimated for the antenna elements with the low-cost radio frequency chain, by interpolating the channel state information obtained for the antenna elements with the high-end radio frequency chain.
