Abstract: In a Multiple Input Multiple Output (MIMO) system, an apparatus and method includes a Tightly Coupled Array antennas (TCA) or Current Sheet Antennas (CSA). Far-field radiation patterns from any current sheet antenna are formed from the combination of the fields generated by a set of currents on the CSA of array port orthogonal modes, such as the Characteristic Modes (CM). The CM currents are generated by excitation of the CSA element ports with corresponding orthogonal voltages or currents (eigenvectors). Since the radiation patterns of the characteristic modes are orthogonal and uncorrelated, multiple signals may be propagated along the radiation patterns of the characteristic modes, each signal using a different characteristic mode or a different set of characteristic modes. Therefore, a CSA antenna utilizing array port orthogonal modes such as array port characteristic modes can support MIMO communications despite the strong mutual coupling among the antenna elements.

Abstract: A method and device for self-tuning scales of variables for processing in fixed-point hardware. The device includes a sequence of fixed-point arithmetic circuits configured to receive at least one input signal and output at least one output signal. The circuits are preconfigured with control scales associated with each of the input and output signals. A first circuit in the sequence is configured to receive a first input signal having a dynamic true scale that is different from the control scale associated with the first input signal. Each of the circuits is further configured to determine, for each of the output signals, an adaptive scale from the control scale associated with the output signal based on the true scale of the first input signal and the control scale associated with the first input signal, and generate, from the input signal, the output signal having the associated adaptive scale.

Abstract: A method includes receiving a pilot signal or a measurement report from a user equipment (UE) or a base station (BS). The method also includes updating a CSI buffer with channel state information (CSI) obtained from the pilot signal or the measurement report, the CSI buffer configured to store previous uplink or downlink channel estimates. The method also includes providing at least a portion of the CSI buffer to a CSI predictor comprising an artificial intelligence (AI) model that utilizes one or more weight sharing mechanisms, the AI model comprising a sequence of layers. The method also includes predicting temporal CSI using the CSI predictor. Depending on the configured output, the method can also include and/or be used for denoising and frequency extrapolation.
