  • Coded-caching in a wireless communication network
    Patent number: 11853261
    Abstract: The present disclosure relates to a serving wireless communication node adapted to predict data files (A, B, C) to be requested by at least two served user terminals (2, 3) and to form predicted sub-data files (A1, A2; B1, B2; C1, C2). In a placement phase, the serving node is adapted to transmit predicted sub-data files (A1, B1; A2, B2) to cache nodes (APC1, APC2), each cache node (APC1, APC2) having a unique set of predicted different sub-data files of different predicted data files, and to receive requests (RA, RB) for data files from the served user terminals (2, 3). In a delivery phase, the serving node is adapted to transmit an initial complementary predicted sub-data file (Formula I) to the cache nodes (APC1, APC2), comprising a reversible combination of the remaining predicted sub-data files (A2, B1) for the files requested.

  • Reconstruction of clipped signals
    Patent number: 11843408
    Abstract: Using information contained in clipped samples from analog-to-digital (ADC) conversion to improve receiver performance, by, for example, reducing the clipping distortion caused by ADCs due to its data resolution constraints. This provides an advantage over existing solutions, which perform suboptimally because the existing solution discard information in tire clipped samples.
