Chapter 4 M-file Descriptions
File ‘4.6.1 Power Line Channel Model [PLRandom.m]’ is used to create the generic
random power line channel model as shown by Figures 4.20 and 4.21.
File ‘4.6.2 Power Line Noise Model [PLNmodel]’ is used to plot the power line noise
model of Figures 4.28. The algorithm is essentially the same as that of file ‘3.9.5 Ingress
Noise Model’ except that noise levels are re-scaled in reference to dBm/Hz instead of
dBmV.
File ‘4.6.3 Channel Capacity [PLCapcity.m]’ is used to calculate power line channel
capacities in a frequency band of between 1 MHz and 30 MHz based on the random
channel model of file ‘4.6.1’ and the noise model of file ‘4.6.2’ as well as a background
nose level of –145 dBm/Hz. C1 is for a transmit PSD of -52 dBm/Hz against the noise
model. C2 is for a transmit PSD of -72 dBm/Hz also against the noise model. C3 is for a
transmit PSD of -52 dBm/Hz against a background noise level of –145 dBm/Hz. C4 is for
a transmit PSD of -72 dBm/Hz also against a background noise level of –145 dBm/Hz.
File ‘4.6.3’ should be run after running both files ‘6.4.1’ and ‘6.4.2’.
