CoGnitive radio network for the smart Grid
transmissions, the significant advantage of employing an ICA-based
approach is that it enables simultaneous transmission for the smart
meters. is eliminates the problem of incurring significant delay in
data recovery. Furthermore, since ICA is a “blind” estimator, it does
not need any prior knowledge of the channel or the pseudorandom
noise (PN) code matrix. As long as the smart meter transmissions are
independent, which is always the case since the meters are spatially
separated, ICA can exactly recover all the smart meter signals.
In this section, smart meter data recovery in the presence of strong
wideband interference is also addressed. Hence, in the event of strong
interference, (5.19) become ...
