We ask for contact info when you comment, but we won’t release that to any...

The Secret Life of Modern RF Signals - Part 4

It’s time to answer a question from a couple of weeks back: “if fading is so random, how can we control and quantify what it’s doing?” In other words, how do we express it, record it and eventually repeat it? One key concept is the idea of Level Crossing Rates (LCR). At a high level, all this means is that a) we choose a level below which we say a fade is a “deep fade”, and b) count the rate at which fades dip below this level. For a Rayleigh-faded signal the LCR is: Equation ...
