摘要：

The PAPR issue has been identified as an important drawback of OFDM systems, which leads to a low energy efficiency in transmission. To overcome it, many PAPR reduction techniques have been studied; in this paper we propose a new method that provides already excellent results regards to state of the art and has also a high degree of flexibility for hardware implementation. This method relies on a Pre Constructed Temporal Signal algorithm, which can reduce the PAPR of an OFDM symbol by modifying the mapping of the subcarriers in a generalized manner. This process can be applied for current standards without any implementation difficulties for FFT sizes up to 8K; it could also be applied without any signal disturbance for future standards using any constellation orders.
