Impact of ADC Bandwidth and Clipping Ratio on COF-PON Systems Based on Spatial Coding and Subcarrier Multiplexing
Analog-to-digital convertor (ADC) clipping ratio code-division-multiplexing (CDM) passive optical networks (PON) subcarrier multiplexing
2011/12/2
In this paper, we analyze the impact of analog-to digital convertor (ADC) bandwidth and clipping ratio on the performance of a 1 Gb/s x 15 user CDM-over-fiber-PON (COF PON) system based on 16-QAM modu...
Volterra Nonlinear Compensation of 100G Coherent OFDM with Baud-rate ADC, Tolerable Complexity and Low Intra-channel FWM/XPM Error Propagation
Coherent Communications Fiber Optic Communications
2010/6/9
Nonlinear tolerance of PDM-OFDM transmission with in-line dispersion compensation, e.g. legacy ultra-long-haul submarine links, is substantially improved by a Volterra non-linear compensation scheme, ...
All-optical parallelization for high sampling rate photonic ADC in fully digital radar systems
Ultrafast information processing Nonlinear optics four-wave mixing
2010/6/9
Optical samples of RF signals are all-optically parallelized for further processing in low-speed electrical digitizers. This technique enables high-rate sampling with no additional jitter and limited ...
A 100G coherent receiver needs 4 56Gs/s ADCs and a tera-OPs DSP which dissipate only tens of watts. This paper discusses the forces pushing towards a single-chip CMOS solution,and the challenges in re...
