Abstract

In this paper, orthogonal frequency division multiplexing (OFDM) with space-time and space-frequency block codes (STBCs and SFBCs) for transmission with multiple antennas is considered. A peak-to-average power ratio (PAPR) reduction method applying the technique of partial transmit sequences (PTS), well established for single-antenna OFDM, together with efficient time-domain search is devised for both STBC- and SFBC-OFDM employing generalized orthogonal designs. Numerical results show that PTS compares well with methods that have previously been proposed for OFDM with STBCs and SFBCs.
