    Wireshark and Bluetooth Device

    Hi Has anyone used wireshark before in order to view the data packets whizzing between the computer/laptop and the Bluetooth device? If so, I am facing a problem with that wireshark as it is not recognizing the Bluetooth device... I'm positive on the fact that the Bluetooth device works, as i...

    Clarification on this image

    Hi.. yeap you'r right. I think it is a spectrum of OFDM.. but im not sure if it is a spectrum of it or is it something else of it :D if you get what i mean. I found it from google images when i types ofdm spectrum.. but i m not sure if it is actually a spectrum of an OFDM or did it just come up...

    What is the ISI channel?

    Re: what is ISI channel? Hello.. Please have a look at the attached pdf.. it says: The lack of guard interval makes OFDM/OQAM more spectrally efficient, but multipath effects must be eliminated by an equalizer. Hirosaki [2] has proved that a single branch fractionally spaced equalizer is...

    What is the ISI channel?

    Re: what is ISI channel? Yes thanks for your very kind explanation.. but if I was to investigate the functioning of OFDM to help in counteracting the effects of delay ICI or ISI? what do i nneed to do? I have already added CP... but i dont think thats enough... Would i need to create Equalizer...

    noise modelling using its pdf?

    i would like to model a noise Background Noise, and it was found that it the probability distribution of the time-domain noise amplitudes resembles the Nakagami-m distribution function. So given the equation of the nakagami pdf equation..will that be sufficent for modelling the noise? i mean if...

    modulation - convolutional channel encoding

    Dear all. I have a question regarding the different modulation type and their relationship with the convolutional channel encoding.. why does the lower order modulation formats (BPSK ...) have their BER graph more towards the lower Eb/No (dB) compared to higher order modulation formats e.g...

    Automated Metering Infrastructure

    Hi all - Could some one kindly explain to me what are these AMI used for? - What modulation type do they use? and any other things that have similarities to communication techniques such as OFDM. Many thanks
