Diversity maximal combining for transparent protocol with Cooperative Network Coding (CNC)

Cooperative communication system is not able fully to solve the problems all about multipath fading, there are many parameters to decrease signal level to the receiver. The author brings the solution to embedded with network coding, this paper focus to enhance research about cooperative with network coding (CNC), using transparent protocol i.e amplify-and-forward (AF) with BPSK and QPSK modulation. We proposed system at the receiver we used diversity maximal combining as known as maximal ratio combining (MRC) with decrease timeslot (time diversity), that combined two parameters between sourcedestination (S-D) and source-relay-destination (S-R-D). Component parameters were bit error rate (BER) and throughput. The simulation results throughput showed that cooperative communication systems with network coding better than cooperative system without network coding.
