A survey on OFDM PAPR reduction techniques for 60 GHz wireless CMOS radio

Multi-giga-bit-per-second 60 GHz transceivers are being developed and implemented on CMOS. OFDM is being considered as the modulation scheme. High peak-to-average power ratio (PAPR) is a major problem for OFDM. This paper reviews and discusses the advantages and limitations of several important PAPR reduction techniques such as coding, partial transmit sequence, clipping, selective mapping, tone reservation, tone injection, and active constellation extension. It concludes that clipping and partial transmit sequence are more practical than other techniques for implementation of multi-giga-bit-per-second 60 GHz wireless communication systems.
