A method to reduce the peak power with sig-nal space expansion (ESPAR) for OFDM system [S], Sumasu, A . & Ue, T. 2000 IEEE 51st Vehicular-lar Technology Conference, Vol. 1.405 to 409 (PC) Orthogonal Frequency Division Multiplexing (OFDM) is an efficient technique for high data rate wireless transmission. However, the OFDM system has a problem that the peak / average power ratio is too high. In order to reduce its peak power, this paper presents a new method called ESPAR. Introduced the principle of this method and
