Blind compute-and-forward

C Feng, D Silva, FR Kschischang - 2012 IEEE International …, 2012 - ieeexplore.ieee.org
Compute-and-forward (C&F) relaying usually requires channel state information (CSI) at the
receivers so that an “optimal” scale factor can be computed for the purposes of decoding. In …
