this the simulation of the relaying technique in all the channels using the amplify and forward and decode and forward protocols. it is also in the channels such as AWGN and also in the raileigh channels.the file also consists of the output graphs of all the simulations which are present in it. -this is the simulation of the relaying technique in all the channels using the amplify and forward and decode and forward protocols. it is also in the channels such as AWGN and also in the raileigh channels.the file also consists of the output graphs of all the simulations which are present in it.
