WebMay 7, 2012 · A low-complexity equalizer which uses a combination of space-frequency minimum-mean-square-error-estimation (MMSE) filter and a pre-whitened maximum likelihood detector (MLD) is proposed for discrete Fourier transform precoded orthogonal frequency division multiple accesses (DFT-precoded-OFDMA) systems employing multi … WebDec 4, 2024 · 3.3 Companded OFDM Signals. From Eq. (), the signal \( S_{p} \left( n \right) \) represents precoded OFDM signals, and PAPR of these signals is minimized up to the single-carrier system because of spreading input data symbols [].Recall that the phase of the signals is distorted by the DFT precoder. Without increasing the system complexity, the …
