  • Publication number: 20240291508
    Abstract: Systems and methods for multiband linearization using kernel regression are provided. In some embodiments, a method includes, for each band of the multiband transmitter: transforming a group of input signals from one or more bands into a constructed input vector space to provide transformed input signals; predistorting the transformed input signals to provide a respective group of predistorted input signals in accordance with a Radial Basis Function (RBF) kernel regression; and transmitting the respective group of predistorted input signals. In this way, some advantages include a semi blind approach as one need not to account for the non-linearity order as in Volterra-based DPD for example, only the memory depth is needed to be incorporated to the input vector space. The computational complexity of DPD is reduced compared to Volterra-based DPD. Implementation complexity is relaxed by means of using a 1D Lookup Table implementation regardless of the number of bands.

  • Patent number: 11936343
    Abstract: Systems and methods are disclosed herein for Digital Predistortion (DPD) in a Multiple Input Multiple Output (MIMO) transmitter. In some embodiments, a MIMO transmitter comprises a plurality of antenna branches comprising a respective plurality of power amplifiers coupled to a respective plurality of antenna elements. The MIMO transmitter also includes one or more DPD systems operable to predistort one or more respective groups of input signals to provide one or more respective groups of predistorted input signals for one or more respective groups of antenna branches. Each group of antenna branches comprises at least two of the plurality of antenna branches. In some embodiments, the MIMO transmitter is a massive MIMO transmitter. Embodiments of a per-branch DPD scheme for a MIMO transmitter that uses Iterative Learning Control (ILC) and kernel regression are also disclosed.

  • Patent number: 11888449
    Abstract: The present disclosure provides a method of linearization for a non-linear system, comprising: a group of steps comprising: inputting an input signal to the non-linear system; obtaining an output signal from the non-linear system in response to the input signal being input to the non-linear system; obtaining a desired signal for the non-linear system; comparing the output signal with the desired signal, to determine whether the input signal is a target signal for the non-linear system to achieve a desired performance; and in response to determining that the input signal is not the target signal for the non-linear system to achieve the desired performance, generating an updated signal in frequency domain by applying a coefficient to eliminate a difference between the output signal and the desired signal, for updating the input signal to the non-linear system. The present disclosure also provides a corresponding device, computer programs, and computer-readable storage.

  • Publication number: 20230378647
    Abstract: An interleaved antenna array configuration in a radio node is disclosed. The antenna array includes a mixture of isolated and non-isolated antenna elements interleaved in each row and each column of the antenna array. Each isolated antenna element is only adjacent to one or two non-isolated antenna elements in each row and each column. Each non-isolated antenna element is only adjacent to one or two isolated antenna elements in each row and each column. By interleaving the isolated and non-isolated antenna elements in each row and column of the antenna array, it is possible to reduce a number of antenna isolators, thus helping to reduce cost and footprint of the radio node. Further, by using a combination of antenna isolators and simplified digital pre-distortion (DPD) actuators in association with the interleaved antenna array, the radio node is able to satisfy stringent radio frequency (RF) performance requirements.
