It's a digital sampling issue, which results in "false data" being "seen" by the digital sensor. That paper is actually not self serving at all, and explains (if you can understand it) the issue very well. It's not an issue of processing the data, it's an issue of getting correct data. No matter how much horsepower you have to process the data, crunching bad data will only give you bad results.
