“…Precoding, as its name implies, attempts to reduce the high PAPR of an OFDM system by multiplying the OFDM data by a precoding matrix prior to modulation. Design procedures for this precoding matrix are presented in [4]. It was shown that one design approach is equivalent to combining pulse shaping with decision feedback equalization (DFE) precoded OFDM.…”

“…There exist many proposed PAPR reduction algorithms for OFDM such as clipping [7], pulse shaping [8], and tone reservation [9]. Selective mapping (SLM) [10] is an example among those algorithms which reduce the PAPR of OFDM signal by multiplying a selected phase-rotation sequence to the frequency-domain signal before transmission.…”

Abstract-Jointtransmit/receive frequency-domain equalization based on minimum mean-square error criterion (joint Tx/Rx MMSE-FDE) is a promising frequency-domainbased technique suppressing inter-symbol interference (ISI) in broadband single-carrier (SC) transmission. However, it changes the frequency-domain spectrum shape and hence increases the peak-to-average power ratio (PAPR) of transmit signal. In this paper, we introduce the selective mapping (SLM), which is typically used in orthogonal frequency division multiplexing (OFDM), to reduce PAPR of SC transmission using joint Tx/Rx MMSE-FDE. The SLM is applied to the frequency-domain SC signal after applying the transmit FDE (Tx-FDE) and prior to inverse fast Fourier transform (IFFT). It is shown, by computer simulation, that the SLM can reduce PAPR without significant effect on bit-error rate (BER). Performance of SLM is also evaluated in various phase-rotation sequence types, in both deterministic and random points of views, and number of candidates. Computational complexity of the proposed transmission scheme employing SLM algorithm is also discussed.Keywords-Single-carrier (SC) transmission; selective mapping (SLM); frequency-domain equalization (FDE); peak-toaverage power ratio (PAPR)

“…Clipping the OFDM signal in the transmitter [5], the tone reservation method [6], partial transmit sequences algorithm (PTS) [7,8], selected mapping algorithm (SLM) [9], pulse shaping [10], random phase updating [11], subblock phase weighting scheme [12], linear scaling [13] and precoding [14]. All of these techniques done for OFDM signals only and little bit of them take MC-CDMA signal in consideration.…”

Abstract-This paper proposes an efficient peak-to-average power ratio (PAPR) reduction method for multicarrier code division multiple access (MC-CDMA) signals by decreasing the possibility of peaks of the subcarriers signals to occur at the same time. The achieved results confirm that the proposed method is capable of reducing the PAPR significantly and, therefore, of improving error performance of the system.
