Adaptive decision feedback turbo equalization and multiuser detection
The analysis of adaptive decision feedback turbo equalization is provided. The turbo detector is a reduced-complexity adaptive turbo equalizer where trellis-based channel equalization is replaced by the adaptive decision feedback equalizer (DFE). We show that for severe intersymbol interference (ISI) the turbo effect (waterfall region) starts at lower SNR relative to the detector applying conventional MMSE DFE coefficients assuming perfect feedback.
