outage probability is related to the channel capacity which returns to the channel model assumed of course, differing from each relay to another makes a relay can contribute in cooperation or not which is mainly based on its outage probability or in other terms outage "capacity" which is limited by Signal To (...)

Ergosic and quasi-static are different. In the quasi-static case the shannon capacity does not exist. THey have to use the outage capacity instead while in the ergodic channel, the shannon capacity is well define since the shannon capacity is the average concept. Hence, the channel must be varied in some (...)

can any body provide me matlab code to plot the capacity CCDf's .
for example SNR of 21dB and outage capacity of 10%..
x axis = capacity ,bits /sec/hz
y axis = probability(capacity>abscissa)
with increasing p(probability )

You are comparing different things. Mutual information determines the capacity of a channel, whereas outage probability is the probability that the capacity is below a certain threshold.

Hi every one!!!
I want to know that what is the idea to simulate the outage probability in the Matlab?
for example, when we want to simulate BER in Matlab we send bits over a channel and then calculate the number of errors and the BER probability. Now, what is the method for outage probability?

in AWGN, we have channel capacity equation:
C = (?)log(1+SNR),
but if we use QAM16,
then the SNR means Eb/No or Es/No or Eav/No?
and even more if we are in Linear-filtering channel,
then how we change the C equation or not?

You only need to have power during the time it takes the uContr. to write into the eeprom and to shutdown. At worst case this would be a couple of seconds. This power can be taken from the power supply capacitors. Probably there is no need for a battery backup, just bigger capacitors.
To detect the outage you must sense the AC voltage. instead of
