Do you mean an M-file or a Simulink model? if the 1st then you use the mex files as people said before me but if the second then you use the Real Time Workshop to create the C code, all what you should do is instead of running it in the normal mode, use the accelerate mode.
Re: wireless lan
WLANs use a certain thing for collision between packets which is CSMA/CA, collision avoidance (Wired LANs use CSMA/CD, collision detection).
awgn noise matlab
as people before me told, you use the awgn noise command in matlab and through its help you will be able to figure out how to use it.
awgn channel
Why dont you use the blocksets avaliable in Simulink, I am sure that there are blockset for AWGN which you can use easily. Simulink is very helpful more than matlab coding to simulate communications systems as well as if there is a certain function that you can't find in the...
About orthogonality, there is 2 concepts for it, the signal is said to be orthogonal in time and also said to be orthogonal in frequency.
But to do mulitcarrier transmission, you should chose only one of the previous.
What i recommend for OFDM is to read chapter 4 in this book: "Theory and...
I have created a model using simulink simulating what you have stated but not the antenna.
what i suggest is that you choose a system (wi-fi, DVB, etc...) and look into the standard and start creating your model.
ofdm+ifft
Zero padding is performed on both sides of the OFDM symbol and acts like a guard band (not cyclic prefix) as for example in 802.11 you have 48 data subcarrier and 3 pilot carrier which makes 52 subcarrier while you perform FFT or IFFT at 64, so you you 'add zeros' at the front and at...
Re: Questions about OFDM.
It suffers from both, as OFDM was created to over the raylieh fading and frequency selective fading.
The concept of sending data parallel to each other at lower data rate which over give a high data rate gets over raylieh fading while the orthogonality of the carriers...
Hey,
I am working on a model for wimax OFDM PHY layer also using the 802.16.2004 standard and was able to design all of it, transmitter and reciever but i have a problem with error rate which i am working on.
what exactly do you need?
