A novel blockwise PAPR minimization algorithm for connected vehicles

In this paper we present a novel algorithm which minimizes peak-to-average power ratio (PAPR) of the orthogonal frequency division multiplexing (OFDM) signal used in IEEE 802.11p like transmission. The proposed algorithm is an extension of the widely known selected mapping (SLM) algorithm. Its novelty relies on performing PAPR minimization jointly in blocks of a few OFDM symbols and transmitting on side information usually required by the SML algorithm on pilot positions. Simulation results prove the usefulness of the proposed algorithm.^1.
