Noise characterization and emulation for low-voltage power line channels across narrowband and broadband

Characterization and emulation of power line noise have attracted interest since long, in both narrowband and broadband applications. Based on existing models, this paper presents a systematic approach to extract and parameterize each subtype of low-voltage (LV) power line noise, which covers the power line noise behaviors across narrowband and broadband. Based on the characterization, an FPGA-based emulator is proposed to emulate power line noise scenarios flexibly. An LV power line noise measuring platform is also presented with sample measurements and their emulation.
