Peak-to-average power ratio (PAPR) reduction is still an important issue in the next-generation mobile communication networks using higher frequency bands. Recently, we have proposed a PAPR reduction technique called blind selected mapping (blind SLM), which does not require side-information transmission and is able to reduce the PAPR effectively without bit-error rate (BER) degradation, for single-antenna transmission and for space-time block coded transmit diversity (STBC-TD). We exploited the fact that PAPR of the signal after STBC encoding and that of before STBC encoding are the same. However, if STBC-TD is combined with transmit frequency-domain equalization (Tx-FDE), the PAPR of transmit signal from each antenna becomes different from those signals before STBC encoding. This is because the transmit blocks are added/subtracted and multiplied with the FDE weights. In this paper, a blind SLM technique is applied to STBC-TD with Tx-FDE. Both orthogonal frequency division multiplexing (OFDM) transmission and single-carrier (SC) transmission (equivalent to discrete Fourier transform (DFT)-precoded OFDM transmission) are considered. Performance of the blind SLM for STBC-TD with Tx-FDE is evaluated by computer simulation, where the simulation results show that blind SLM techniques can lower the PAPR of STBC-TD with Tx-FDE without causing BER degradation. |
