- Abstract
- Conventional decode-and-forward (DF) relaying with multiple relays can increase the reliability by creating a virtual antenna array, but induces the capacity loss. We introduce a DF relaying with distributed beamforming (DBF) which has better reliability than conventional DF relaying as well as increases the capacity. Under the power constraints of each relay, not the total sum power of all relays, we And the optimal DBF weights, for each relay, which maximize the received signal-to-noise ratio (SNR) at the destination. We derive an approximated probability density function (PDF) of received SNR and analyze the outage probability in Rayleigh fading channels. Numerical results show that derived probability is very well matched with the simulation results.
