A scheme for cancelling intercarrier interference using conjugate transmission in multicarrier communication systems [PDF]
, 2007 To mitigate intercarrier interference (ICI), a two-path algorithm is developed for multicarrier communication systems, including orthogonal frequency division multiplexing (OFDM) systems. The first path employs the regular OFDM algorithm. The second path

Pseudo-doppler aided cancellation of self-interference in full-duplex communications
Frontiers in Signal Processing, 2022 In this work, a novel scheme is proposed to enhance the self-interference (SI) cancellation in full-duplex communications. Beyond conventional SI cancellation schemes that rely on the SI suppression, our proposed scheme exploits periodic antenna ...

Double logarithmical corrections to beam asymmetry in polarized electron-proton scattering [PDF]
, 2007 The up-down asymmetry in transversally polarized electron proton scattering is induced by the interference between one and two photon exchange amplitudes. Inelastic intermediate hadronic states (different from one-proton state) of the two photon exchange
