摘要：
We propose a low-complexity block turbo equalizer for orthogonal frequency-division multiplexing (OFDM) systems in time-varying channels. The complexity of the proposed algorithm is linear in the number of subcarriers by exploiting the band structure of the frequency-domain channel matrix. The presented block turbo equalizer is based on a soft minimum mean squared error (MMSE) block linear equalizer (BLE).
