A system and method for efficiently performing a data encryption operation in an electronic system preferably includes a processor that may initially create an encryption structure in a memory device. The channel estimator uses the first subset to train, via initializing and updating, the channel estimator to stabilize the channel estimate. The hydrogenation occurs under these supercritical conditions, thereby overcoming the hydrogen solubility and mass transfer problems typically encountered in hydrogenation methods at subcritical conditions, wherein hydrogen must be pressurized into solvent to reach the polymer.
