Abstract: | Amplify-and-forward relay techniques combined
with OFDM (Orthogonal Frequency Division Multiplexing)
modulations are being considered for broadband
wireless systems since they allow simple relay systems
suitable for severely time-dispersive channels. However,
since they rely in OFDM-based signals, these techniques
are prone to nonlinear distortion effects.
In this paper we consider OFDM-based amplify-andforward
relay systems with strong nonlinear distortion
effects at both the transmitter and the relay node and
we present a simple, but accurate, analytical method for
characterizing the distortion levels at the subcarrier level. OFDM, , amplify-and-forward, nonlinear distortion effects |
