SENSING AND/OR COMMUNCATION IN A NETWORK BASED ON AFFINE FREQUENCY DIVISION MULTIPLEXING

원문 (중국어)

The present disclosure relates to sensing and/or communication in a network. The disclosure proposes a sensing device, a sensing device transmitter, a sensing device receiver, a network device, a network, and corresponding methods for operating said devices. The sensing device is configured to generate an affine frequency division multiplexing (AFDM) signal comprising a set of chirp carriers that are orthogonal in a discrete affine Fourier transform (DAFT) domain, and transmit the AFDM signal, wherein the set of chirp carriers is generated based on an inverse discrete affine Fourier transform (IDAFT) and wherein the set of chirp carriers comprises a first subset of chirp carriers that are pilot signals for sensing, and a second subset of chirp carriers that are nulled.
