Design And Performance Evaluation of Multiple AF-Relay Processing in Multi-Cell Environment

초록

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.
