Error Performance Analysis Of Physical Layer Network Coding With Transmit Diversity At Relay
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
We analyze the error performance of the physical layer network coding (PNC) protocol with transmit diversity in bidirectional relay networks for binary phase shift keying (BPSK) over Rayleigh fading channels. It is assumed that a bidirectional relay network consists of two sources at transmitter and two sources at receiver and a relay consists of two antennas, where each source node has a single antenna and operates in a half duplex mode, and the PNC over finite GF(2) is employed. In this system, since the signal estimation of the multiple access channel (MAC) at the relay is given by the sum of two exponential functions. Then relay transmit in the form of transmit diversity (alamouti) to the source. Then finally we derive the capacity for system model. Finally we obtain outage probability, outage capacity for the end to end average bit error rate.
