...On the other hand, the relay may generate the “XOR”ed information of the multiple-source streams in the context of both the original bit-based classic network coding (CNC) scheme [12], [13] and the modified waveform-based physical-layer network coding (PNC) arrangement [14], [15]....

...[4], that adaptively changing the network coding map used at the relay according to the channel conditions greatly reduces the impact of multiple access interference which occurs at the relay during the MA phase and all these network coding maps should satisfy a requirement called exclusive law....

...For values of (HA, HB , HC) in the neighborhood of the singular fade states, the value of dmin ( CAB ,HC ) is greatly reduced, a phenomenon referred to as distance shortening [4]....

...The work in [4] and [7] shows that for the two-way relaying scenario, the 4(2) possible pairs of symbols from 4-PSK constellation sent by the two users in the MA phase, can be clustered into a clustering dependent on a singular fade coefficient, of size 4 or 5 in a manner so as to remove this singular fade coefficient....
