  Abstract

In the 3GPP LTE systems, SC-FDMA is adopted for the uplink owing to its good PAPR efficiency. In the frequency domain, however, the performance of SC-FDMA is degraded due to frequency selective fading. As a compromise, a Hybrid OFDMA/SC-FDMA was proposed in the LTE-Advanced systems. Hybrid scheme uses SC-FDMA in the edge of cell area, while it uses OFDMA nearby the base-station. In this paper, uplink relays based on hybrid scheme is proposed to increase the performance of the 3GPP LTE systems. With different positions of mobile and relay, the proposed scheme can adaptively select SC-FDMA or OFDMA to improve the link performance. Our simulation results show that the proposed scheme achieves a better performance in terms of end-to-end BER and power consumption.
