Distribution of Signal Strength for Rician Fading
Expressed in terms of the local-mean power and the Rician K-factor, the pdf of the signal amplitude becomes
This Special Purpose Embedded Calculator calculates the distribution, i.e., the pdf integrated from zero to a thrshold value. This presents the probability that a signal
amplitude drops below that threshold value.
Outage Probability for Rician Fading
- Note 1: enter a large negative number (e.g. -100 dB) for the K factor to model Rayleigh fading.
- Note 2: Do you see a probability larger than unity?
For small outage values, there is an exponent ("e-..") in the outage probability.
Some browsers may hide this outside the visible field
if they present too many mantissa bits. If you are in doubt, place the cursor
in the Outage Probability field and move to the right, beyond the visibile area.
Any exponent will scroll into the window.
- Convert LOS amplitudes and sigma to the K-factor and power.
