    Hey Irfan.These videos are really very informative. You seem to be referring to videos on charging policies and QoS in your lectures but doesn't seem they are on your channel. Any chance of making them public if you have them handy. Again thanks a bunch for these videos!

  • @grjesus9979
    @grjesus9979 3 роки тому +1

    If you use any type of modulation (e.g QPSK, 64QAM...) then which is the basis signal (raised cosine?). The way you proposed it here it is just a rectangular wave from [0, T] and therefore ISI exists (this is not useful) and also if you have a multipath channel there will be also ISI.
    I find this good as an introduction of how OFDM works but you skip many key facts.
