Cooperative relaying technique has shown potential in enhancing coverage area and reliability of transmission by forming virtual arrays. Opportunistic relaying tries to utilize best available channel between source and destination. Outage performance of relay based system can be improved through proper allocation of power and positioning of relay node. Analytical expression for outage probability...
BER performance of cooperative relay network, employing infrastructure based fixed relays having multiple antennas has been investigated. Closed form expression for average BER has been derived, when destination is assumed to perform selection combining of the signals, received from direct path and through relay path. BER expressions are derived for both the cases of selection and maximum ratio combining...
