can anyone plz tell me what is outage capacity and how to find it in matlab ? waiting,,,,,
could u plz tell me about outage capacity too ?
I am working on relay selection. I am trying to understand the relationship between BER and outage probability.
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 (...)

hello everybody, my name is narender, a b.tech final year degree. iam doing my project on pre piad energy meter. i am facing a trouble with the design. brief about my project. there will be an energy meter ic which wil be converting the instantaneeous load into pulses and a microcontroller which will be counting those pulses and when ever the c
Q: what does delay constraint for the user mean ??? Ans: Delay with respect to the fading is that... When a signal travels in all directions & meets to the reciever antenna... the antenna will get the same signals from different paths... So as a result of this some signal which are recieved after some fraction of second.. will
Dear, I am also stuck in the similar problem as yours and want to draw various graphs like 1. rate sum capacity vs number of users 2. outage probability vs number of user 3. outage probability vs snr have you able to solve the problem if yes can you please help me as well. P.S i have simulated the basic capacity (...)
hi, all we use the shannon capacity and outage capacity in different case. can anyone talk about what decides the channel is ergodic or no-ergodic. is it the propagat environment or others? thanks:D Hi, As many people said above, ergodic channel has a long term constant bit rate. Actually, guys who know rand
outage probability is a crude measure of performance. It is defined as the probability when mutual information is less than the given threshold. The importance of outage probability is that when outage occurs, there is more likely to have decoding failure. In other words, it is a typical error.
hi , i read some paper about wireless relay communications . and outage probabilty is the one of evaluation parameters . from the expression , thai is Pr(I
hello, I didn't understand why if the mutual information between source and destination is less than the rate an outage occur?
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?
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 )
Maximum diversity of the system is the maximum vanishing exponent of SNR in the outage probability. Any scheme that that achieves the same exponent order is said to achieve full diversity.
The Iterative Solutions Coded Modulation Library (ISCML) is an open source toolbox for simulating capacity approaching codes in matlab. It has been developed by Matthew Valenti. It is licensed as free software under the lesser GPL license. The toolbox contains support for the followi
Hi,sir you are a person who frequently upload the various codes (MATLAB) for us junior students. So I thought I might request you for a personal favour. Sir, I am a student of UG at NUST and wanted some help for my project. Actually as part of my thesis project i am supposed to do following tasks for any wireless system (ofdma preferably) 1)sn
Arif Khan and others Can you please explain to me that in a graph of outage probability, where x-axix is SNR in dB scale and on y asix there is semilogy y of outage probability,, How to find the diversity order by using slope formula ?? please help. BR,

Hi, it depends on the channel gain i.e., H matrix. Let me give you a brief idea: Definitions of Ergodic & Non-Ergodic channel: Ergodic channel The channel gain process is ergodic, i.e., the time average is equal to the ensemble average. In other words, the randomness of the channel gain can be averaged out (removed) over time. So long-
currently, i m considering BER, but i intend to expand the comparison to outage probability. as for now i have developed a basic frame work and just want to know if it is correct.
cycle use is the term used when the battery is delivering the voltage to the load...... and standby is when the system is in idle state........ ---------- Post added at 22:02 ---------- Previous post was at 22:00 ---------- "Cycle Use" - direct power source: Cycle Use It can provide the power supply to power
If I were to use these two together with a 12V Car Battery out of the vehicle, do you think this would work ? The Power Inverter connected to the battery & Battery Charger would be plugged into the power inverter & the battery charger connected to the car battery... Basically a loop.. I would then use just a couple CFL'S in my house in the event
So the charging circuit is just a voltage regulator? Isn't there a current limiter that controls the charge current? Alex Yes it is just a regulator. Here is the input circuit attached. 67351 The user says he needs only an ampere or so to keep the Router and Cable modem ON. I have a small UPS (APC Bac
UPS during power outage fast switch and supply power from internal inverter. Power consument continue to work, like nothing happen, if main power is back UPS switch supplying power to mains and charge internal battery. Switching from mains to internal inverter is in time in 4ms range. UPS is device which give power to power consument from mains or
How to make (build) ATS (Automatic Transfer Switch) ? I want to switch off my generator's output power & switch on the electricity (provided by the Govt) when the electricity shortage (outage) is over . Can i make that circuit ? Also, if i want to completely shut off the generator then can it be done too ?
Hello, im currently designing a 12V battery charging circuit. The simple summary: This circuit will charge 2 12V battery & when there is power outage, the 2 batteries will supply to the equipment. The charging circuit is up and running. But now im given a new task - when the battery is 90-95% fully charged, the battery will be cut off from th
It is a big wall clock based on Atmega8. Its dimensions are: 180x70x18mm. Presented clock displays not only hours and minutes, but also blinks the colon and has automatic control of the brightness depending on the lighting (th
correction table is added in case o/p is less and deducted in case the o/p is more fore each pulse Is this method more precise than seperate complete tables? I guess there is more error introduced in values of sine table generated due to small values of error table causing distortion. How about pi correction? A
Are NiCd batteries superior to NiMH batteries for emergency lighting unit use?.......... the following seems to suggest that it you agree? As discussed, i was looking into NiMH vs NiCd cells for our Emergency Lighting Unit...... Unfortunatley, NiMH is not looking suitable for Emergency use, because Emergency use requires the batter
