Nonlinear decision-feedback equalization for OFDM in a fast fading channel

Joint low‐complexity equalisation and CFO compensation for DCT–OFDM communication systems based on SIC

“…On the other hand, the computational complexity of the non‐linear equalisation can be reduced using the BMA concept [24]. In [40], the authors presented a non‐linear DFE with noise clipping to mitigate the large PAPR and preserve the BER performance of the OFDM system.…”
