thank you very much mohammed the problem is that even the standards is not clear about the specifications it is like a draft they delete sth and add sth every day it is hard to understand what exactly needed for the implementation.
thank you very much yeah it was so helpfull. If you dont mind can i ask you one question what is the reason beyond that matlab code. they said it is done for the interleaver in order to achieve distribution for subcarriers. but when i try it for two ofdma symbol it gives me error. And the bit...
thank you very much for quick answer but the thing I am wondering that is there any importance of using the qpsk in mapping for example if i want to use mQAM what will be difference? and second question the location of the pilots are important or not? and the last when i see pilot insertion...
Rama I am doing my final year project in this topic as well. Did you make any progress. What are you trying? can you be more specific? for example which size of ifft are you using?
hello guys , I want to implement the mobile wimax physical layer via matlab/simulink I know which block that I have to use but I have some problems with unclear specifications .For example to test it at least how many bit I have to generate and if sb see the fixed example in simulink according...

Re: rf bug detector
I controlled it and all of the pieces are in the correct place. I measure the current and it was 70mA how can I fixed it and yes u right its sensitivity so bad again how can I fix it. I try it with mobile phone it about 900 Mhz there was some changing in the loudspeaker...
Re: rf bug detector
I measure all of the pins and resistor which u mentioned above and let me to share with u potantiameter:1.8
base of transistors:-2
d1 cathode:1.8
r12:1.8
pin1 4.7(when ı open the transmitter it is become 5.2)
pin14:2.9
pin8:3.3
r13:3.6
r11:3.6
Re: rf bug detector
yes he is corrected but absolutely it is not working. I get help to solder it from an expert soldering I made it two times and two times ithe loudspeaker is make voice without signal when I put the battery it starts to work. I will fail if has not working till next week:S
Re: design 4 electronic eaves dropping device detector..plz
what do u mean with that? if I test is with fm transmitter with 100 Mhz it will not picked it up.
rf bug detector
I made and put all of the components. but the loudspeaker is working when I put the battery and it doesnt detect anything how can I fix it. the project is take place in that link http://english.cxem.net/guard/guard28.php please help
