Novel low resolution ADC-DSP optimization based on non-uniform quantization and MLSE for data centers interconnects Academic Article uri icon

abstract

  • A new generation of combined ADC-DSP scheme is proposed. It is based on a novel non-uniform quantization method, optimized for MLSE based receivers. This inclusive optimization enables the use of extremely low-resolution analog-to-digital-converters devices, which form a major bottleneck in high speed optical communications receivers’ architecture. Through Monte-simulation it is demonstrated that the proposed method leads to a significant SNR gain over conventional designs, and may provide low cost and low power consumption digital implementation solution for datacenter interconnects.
