Another way: from physics, for a radial (approaching) velocity V r ,f D = f 01cV r, 1 =f 0V r f 0V rc , V r cBut V r = V cos and c = f 0 sof D = V cos Often, V and will vary with time, so f D will varycorrespondingly, causing Doppler spread. Often this is modeledstatistically. In general, the Doppler spread characterizes the rateof channel variations.EEL 6593/Fall '95/Paul Flikkema/USF 3
