High Peak-to-Average Power Ratio (PAPR) is one of the challenging issues for Orthogonal Frequency Division Multiplexing (OFDM). In this paper, we propose a PAPR reduction technique, which combines Partial Transmit Sequence (PTS) and companding techniques. Some simulation results are presented, commented, and compared with the results obtained applying PAPR reduction methods already proposed in ...

Although orthogonal frequency division multiplexing (OFDM) is an efficient wireless transmission system, it suffers from a crucial drawback namely high peak-to-average power ratio (PAPR) that limits transmitter power efficiency. Thus, different PAPR reduction algorithms have been introduced. Partial transmit sequence (PTS) is the most attractive solution which can provide good PAPR reduction pe...

Abstract-Orthogonal frequency division multiplexing (OFDM) is preferred for mobile communications applications due to its increased data transmission capability. At one hand, it has advantages of being robust to multipath fading and possessing high data rate transmission capability, on the other hand it suffers from high peak to average power ratio (PAPR). In this paper FPGA implementation of c...

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation technique which can be used for both broadband wired and wireless communication. OFDM is now becoming widely popular among the multicarrier communication systems because of its immunity to Inter Symbol Interference (ISI), Inter Carrier Interference (ICI), impulse noise etc. and also it has high spectral efficiency.

The rst lower bound on the peak-to-average power ratio (PAPR) of a constant energy code of a given length n, minimum Euclidean distance and rate is established. Conversely, using a non-constructive Varshamov-Gilbert style argument yields a lower bound on the achievable rate of a code of a given length, minimum Euclidean distance and maximum PAPR. The derivation of these bounds relies on a geome...

The theoretical analysis of the peak-to-average power ratio (PAPR) distribution for an orthogonal frequency division multiplexing (OFDM) system, depends on the particular waveform considered in the modulation system. In this paper, we generalize this analysis by considering the generalized waveforms for multi-carrier (GWMC) modulation system based on any family of modulation functions, and we d...
