Sign-Compute-Resolve for Random Access [PDF]
, 2014 We present an approach to random access that is based on three elements: physical-layer network coding, signature codes and tree splitting. Upon occurrence of a collision, physical-layer network coding enables the receiver to decode the sum of the ...
