- 초록
- Frequency switched transmit diversity (FSTD) is a simple diversity technique which can be easily combined with existing multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) schemes to support an increased number of transmit antennas. For the MIMO-OFDM based on FSTD, this letter proposes a reduction scheme of peak-to-average power ratio (PAPR). The proposed scheme generates signal candidates (SCs) by mapping the subparts of OFDM symbols onto multiple antennas under the criterion of reducing correlation among the SCs. The proposed scheme is shown to provide good PAPR performance and to allow a low-complexity detection of the transmitted SC without side information. © 2010 IEEE.
