SER Analysis of Two-Hop Physical Layer Network Coding with 16QAM Modulator

The interference is the major factor disrupting the sending of information in wireless networks. To get better performance for these networks as well in the conventional case as in cooperative one, all the necessary ways must be used to eliminate network interference. This article deals with the concept of Physical Layer Network Coding (PLNC). It is a way to exploit the operation of Network Coding (NC) that occurs naturally in the superimposed electromagnetic waves (EM). It is a simple physical effect when several EM waves meet in the same physical space, they are mixed together. This mixture of EM waves is a form of NC produced by nature. Hence, the situation will be reversed and the interference will be a beneficial way to help the relay when sending information. This paper focuses on the Symbol Error Rate (SER) Analysis of PLNC in the case of 16QAM modulator. It will exploit in detail the concept of mapping (modulation/demodulation) and will demonstrate it
