Practical issues in multi-user physical layer network coding
Giuseppe Cocco, Nader S. Alagha, Christian Ibars, Stefano Cioni · 2012
We address several implementation issues related to multi-user physical layer network coding, in which the symbol-synchronous collision of an arbitrary number of signals is decoded. In particular we study the effect of frequency and phase offsets, the imperfect symbol synchronization of the colliding signals and the estimation of frequency and phase offsets and amplitudes in the presence of more than two colliding signals.
