Side information embedding and detection scheme for selected mapping based single‐carrier frequency‐division multiple access systems

Generalised precoding method for PAPR reduction with low complexity in OFDM systems

“…Although all the elements of the PM can be extracted from the first column of PM, the definition of P i, 0 in (2) provides an optimal solution in (19). In the precoding method [9], Slimane refers to the PM which uses (2) as Precoder 1, and defines another PM based on other function, called Precoder 2.…”

“…The soft companding technique such as Mu-Law companding [14,15], non-linear companding [16], exponential companding [17], and new companding using the airy special function [18] apply a nonlinear transformation to limit high peak value. The selected mapping (SLM) [19,20] and the partial transmit sequence [21][22][23], which comprise the representation of multiple signals, were proposed to obtain low PAPR but both methods employ complex circuits and require transmitting side information to the receiver.…”
