Abstract :
For multiple half-duplex amplify -and-forward (AF) relays in cellular communications, a statistical power allocation (control) method is designed to minimize network power under the relay-transmit-power and the signal-to-interference-plus-noise ratio constraints. Computer simulation corroborates that the designed relay processing yields significant performance enhancement and network power reduction compared to a system with plain AF relays and a direct communication system without relays.
