Physical layer network coding simulates how MPSK draws constellations. Using matlab to realize ... how do the following points map to the above points? Ask for guidance .

If it is a baseband signal, it can be directly scattered, otherwise it needs demodulation.

a=randi(2，[ 1000， 1])- 1；

A=pskmod(a，2)；

A=awgn(A， 10)；
