In the fourth generation mobile communication system, the frequency band higher than the bands already assigned for IMT-2000 is expected to be utilized. However, higher radio frequency causes larger propagation loss.
To cope with the problem, Amplify-and-Forward relay transmission has been investigated. In this letter, a novel transmission diversity scheme in an AF relay system is proposed. In this scheme, the frequency of an OFDM signal at the relay station is shifted. The different amount of frequency offset is used in each relay station and the signals from the relay stations are separated and combined by MMSE detection at the base station. The numerical results obtained through computer simulation show that diversity is realized and the BER performance is improved by $1-2 \ \mathrm{dB}$ at the BER of $\mathbf{10^{-2}}$. |
