Abstract :
We consider a source-destination pair assisted by multiple decode-and-forward relays without channel state information at transmitter (CSIT). We investigate three schemes exploiting spatial diversity including multiple-relay cooperation (MR-Coop), conventional multiple-relay relaying (MR-Relay), and multiple-input-single-output (MISO). The total power is equally allocated to transmission partners without the knowledge of CSIT. Moreover it is practical for relays to decide whether or not to assist transmission with the knowledge of channel state information at receiver (CSIR). We then deal with a typical path loss exponent of 3, present the corresponding computational methods for outage probability. This method is based on characteristic coefficient, which is simpler than the existing methods which are based on calculating probability density function. Simulation results are provided to demonstrate the validity of our analysis, and also show the cooperative scheme can effectively exploit multiple-channel diversity and path loss saving to combat the fading.
