Quantization Noise Free Channel Equalization for Low-Oversampled Quantization Noise Shaping in DMT Signal Transmission
This paper proposes a quantization noise separation method to mitigate residual noise impact on channel equalization in low OSR noise shaping systems. 1.49 OSR BER decreased from 5.2e-3 to 2.6e-3, achieving HD-FEC at −4dBm ROP.
