A Low-Complexity Sliding-Window Turbo Equalizer for Nonlinearity Compensation


TR Image
Abstract:

We propose a low-complexity turbo equalizer consisting of a sliding window MAP estimator, and a low overhead LDPC decoder. By utilizing 2nd order statistics, we obtain 2.5 - 4dB gain with additional improvement with turbo loop.
