Two techniques of the most known ones for peak to average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) are selected mapping (SLM) and partial transmit sequence (PTS). Both schemes were proposed as distortion less PAPR reduction algorithms. However, it has been an argument to prove which scheme is the most effici...

... Figure 3, for example, shows the CCDFs of two original and modified OFDM signals with number of subcarriers 256 and 1024. It is shown in fig 3 that 0.01 percent of unmodified OFDM data blocks with 1024 subcarriers have PAPR of 12.4 dB. After the modification is implemented for the same OFDM signal with the same number of subcarriers, 0.01 of the modified OFDM data blocks have PAPR of ...

A new transmitter side windowing function to reduce inter-carrier interference (ICI) in orthogonal frequency division multiplexing (OFDM) systems with carrier frequency offset is proposed in this paper. The results show that the proposed method outperforms all the recently proposed windowing functions in the literature in terms of average signal po...

In this paper, an enhanced greedy bit and power allocation algorithms for orthogonal frequency division multiplexing (OFDM) communication systems are introduced. These algorithms combine low complexity greedy power allocation algorithms with a simplified maximum ratio combining (MRC) precoding technique at the transmitter for maximizing the average...

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...

Existing 64-QAM Golay complementary pairs, each having impulse-like aperiodic auto-correlation sums, have been used to generate codebooks in code-keying orthogonal frequency-division multiplexing (OFDM) communications for the peak-to-mean power control. As a generalization of the 64-QAM Golay complementary pairs, in this paper, 64-QAM complementary...
