Synchronization and Channel Estimation for OFDM Systems with Transparent Multi-Hop Relays

Kyung Soo Woo; Hyun Il Yoo; Yeong Jun Kim; Heesoo Lee; Hyun Kyu Chung; Yong-Soo Cho

In this paper, the effect of a propagation delay resulting from the use of an OFDM system with a transparent mobile multi-hop relay (MMR) is initially analyzed. Additionally, a channel estimation technique for the OFDM system with throughput enhancement (TE) MMR or cooperative MMR is proposed. Secondly, the effect of a Doppler shift caused by a mobile MS is analyzed and a compensation technique for the carrier frequency offset (CFO) in the OFDM system with TE MMR is proposed.
