  • 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.
    Type: Grant

  • Self-interference suppression in full-duplex MIMO relays
    Patent number: 8570933
    Abstract: A method, and an apparatus, for self-interference suppression in a relay for wireless communication, wherein the relay is arranged for receiving a signal r(n) transmitted from a transmitter, and for transmitting a self-interference suppressed transmit signal xr(n) to a receiver. The self-interference suppressed transmit signal xr(n) is achieved by determining a receive suppression filter matrix Wr, determining a relay amplification matrix G, and determining a transmit suppression filter matrix Wt, and then applying the suppression filters and the amplification matrix to the received signal r(n).

  • Self-Interference Suppression in Full-Duplex MIMO Relays
    Publication number: 20120106405
    Abstract: A method, and an apparatus, for self-interference suppression in a relay (300) for wireless communication, wherein the relay (300) is arranged for receiving a signal r(n) transmitted from a transmitter (301), and for transmitting a self-interference suppressed transmit signal xr(n) to a receiver (305). The self-interference suppressed transmit signal xr(n) is achieved by determining (402) a receive suppression filter matrix Wr (302), determining a relay amplification matrix G (303), and determining (403) a transmit suppression filter matrix Wt (304), and then applying the suppression filters and the amplification matrix to the received signal r(n).
