Abstract
Provided is a relay-synchronization signal (R-SS) transmitting apparatus and method in an orthogonal frequency division multiplexing (OFDM)-based Long Term Evolution Advanced (LTE-A) system having a multi-hop relay. The R-SS transmitting apparatus generates a R-SS having the same peak-to-average power ratio (PAPR) characteristic as a synchronization signal (SS) and having a lower correlation characteristic than the SS, using the SS for synchronization with a terminal, for synchronization between a relay and a base station, for a synchronization between a relay and a subordinate relay, and for monitoring, by a relay, an adjacent base station or an adjacent relay
