CDMA starts @ exactly 09:00. The explanation was crystal clear. Thank you sir. I believe it is not ‘chips’, but ‘chirps’ @ 30:10

best explanation sir but i have doubt that is in reference books it is mentioned that pn codes are non-orthogonal codes but you mentioned it has orthogonal code

Hi, at 38:10, in codes C1 and C3, there is orthogonality *provided* that the encoders are synchronized. If you time-shift C1 by one bit-time, it will no longer be orthogonal with C3. How can this be worked around? Surprisingly, C0 C1 and C2 remain orthogonal even if time-shifted (i.e. with asynchronous clocks). Is this statement correct? Wouldn't it be smarter to forego C3 and stick with just C0 C1 and C2?

How can we transmit 2 symbols at the same time and of same frequency? pls explain....

I think the two symbols are added as one symbol to transmit, not transmitting two symbols
