Those interested in noise canceling might be interested in what the rest of the communications industry is doing with exotic integrated circuit systems that kill noise by inverting and adding it to the signal at the antenna input.
There's one completely IC-based system that's now available: http://www.elektor.com/news/rf-noise-canceller-ic-banishes-interference.2516 47.lynkx The good news is that it is on one chip and reportedly quite effective. The bad news for the casual homebrewer is that the chip measures less than 1mm (<0.04") on a side.
