Noise modeling for power line communication model

Random Channel Generator for Indoor Power Line Communication

“…11 , lc 21 , lc 32 , lc 43 , lt 24 [6,7,9,9,6,6,8,8,7,6,10,5,6], where lt ij -length between T i and C j , lc ij -length between C i and C j (see Fig.2.). Results for medium topology with 7 sections:…”

“…Power line channel is a very harsh and noisy transmission medium [11]. The power line channel is frequency-selective, time-varying, and is impaired by noise.…”

“…Existing communication technologies can be applied to the Smart Grid, new communication protocol and enhancement of the existing protocol are necessary to capture the unique characteristic and requirement of Smart Grid. Sufficiently precise computer models of PLC systems will make the process of selecting and deploying new telemetry and management technologies for Smart Grids markedly more effective [13]- [15].…”

Bit Error Rate Performance in Power Line Communication Channels with Impulsive Noise

“…The Cyclic Prefix (CP) is inserted to reduce Inter-symbol interference (ISI). The multipath channel model has been used as given in (2). Background and impulsive noise are injected through the channel.…”

“…However the PLC channel is not conducive to high speed data transmission due to attenuation and interferences from various sources [1]. In [2] different types of PLC noise sources are modelled in Matlab/Simulink, among these the background and impulsive noises are the main source of interference resulting in signal distortion. The background noise can be modelled as an Additive White Gaussian Noise (AWGN) and the impulsive noise is based on the Middleton Class A noise model [3].…”
