I do not know what the "lossy" part has to do with this. If you want to just 
simulate noise in the message itself, then add AWGN noise to the message 
before the receiver end. This is the most basic way to add noise to a 
message which account to noise in the transmission channel and to thermal 
noise at the receiver side as well
