A powerful and real time PAPR reduction process for energy efficiency improvement in OFDM communication systems
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.
