I guess:
Transmit SNR= transmitted power without any attenuation/thermal noise power in the transmitter electronic circuit.
Receive SNR= received power/end-to-end total noise
No, I do not think so. I think that the router forward the ACK without knowing any additional information because the router main functionality is in layer-3 and the ACKs are in layer-4.
Does that make sense?

I mean that the sequence number and the ACK number are in...
Re: Network problem - he page is not loaded unless i restart
Try to full scan your PC for viruses, If the issue is still existent, you can use another browser, for example use firefox instead of Internet Explorer. If you still face the same problem, try to remove add-ons and re-install them...
You can try to count a number of packets, for example 1000 packets, and also count the number of re-transmissions within those 1000 packets and simply divide the number of the re-transmissions by 1000 to get the packet error rate.
You can also count the packets with CRC failed and divide the...
If you use a hub, then your topology will be physically star but logically bus.
So If you use a switch your topology will be logically start and it will not need CSMA/CD as you said. So if you use FDM on a bus topology, it can be considered as logically star as it is impossible for collisions to...
Re: common Drive
Right click on My Computer>Manage>Disk Management
And then you can select the type of drives you want, for example RAID 0, RAID 1 and so on.
Do not worry it will not affect the BER calculation but of course the symbol error rate (symerr command) will be different, I have implemented the whole WiMAX using this modulation function and it is accurate.
What you hear is the rate of the bursts of data.
The burst time is 8 time slots.
The time slot is 0.557 ms
so the burst time is 4.456 ms, so the rate of bursts is in the audio range of frequencies, so we can hear it. Also the signaling of the call setup is on the same range of audio frequencies.
Re: rayleighchan usage
There is a tool in MATLAB that sketch the frequency response and the impulse response of the channel.
You can use channel estimation and equalization.
The least square is the simplest method and it does not require an intensive processing, you can use it.

You can implement the MAC layer of the WiMAX, but to do that you have to have a simple model of PHY layer of WiMAX to apply the scheduling of resources and the adaptive modulation and coding.
Good luck
Eb/No is a normalized signal-to-noise ratio (SNR) measure, also known as the "SNR per bit".
Eb/N0 is equal to the SNR divided by the "gross" link spectral efficiency in (bit/s)/Hz
The relationship between them is simply as the following:
SNR= Eb/No * Rb/BW
Rb--> Net bit rate.
BW --> Channel...
First of all you have to learn VHDL very well, as it is the main code that is used in programming the VHDL kit.
You and your team have to specify the appropriate kit to buy.
Then you have to study the different blocks of the CDMA system transceiver to be able to implement it.
The main challenge...

This book contains the different puncturing patterns used in the WiMAX standards for different code rates 1/2,2/3,3/4 and 5/6.
The concept of the puncturing is very simple as I stated, and the MATLAB 2008 has a filed in the convenc command for the puncture pattern, If...
