where W(k) denotes the k th subcarrier additive white Gaussian noise (AWGN) sample with zero mean and variance σ n 2. For analytical simplicity, we assume that the channel is estimated and compensated and therefore, the signal after frequency-domain equalization can be written as S ′ ( k ) = X ( k ) + ∑ i = 1 K P i E i ( k ) + W ′ ( k ), k = 0, 1,..., N - 1, (12).
The equalized symbol (tilde {textbf {s}}_{k}) can be written as: tilde{s}_{k} = textbf{p}^{H}_{k} textbf{y} - textbf{q}^{H}_{k}hat{textbf{s}}_{k} quad text{with} quad kinleft[1,Mright], (13) Figure 3 Turbo equalization with MMSE-IC equalizer.

Residues can be written as.
Then, the first LGI samples are omitted and followed by a cyclic shift operation, which can be written as s [ k ] = s [ mod ( k + L GI − 1, MK ) ], for k = 0 … MK − 1. Next, an L-point FFT operation is performed so that a frequency domain equalization (FDE) can be straightforwardly envisaged.
