can TDD be used for real time voice communication, just like we have in FDD. As in TDD both TX and RX is done in one complete channel with TX in one time slot and RX in other time slot...and some time gap in between, for transition from Tx to RX and vice versa
What is the difference between PCM and other modulation techniques like PSK, FSK etc... I understand how they are done, but my question is where do they fit in communication system. lets say we have binary sequence we can use PCM and transmit it..then why do we need other keying techniques. do...
thanx for replying,
i think Gaurd interval and CP is same thing and used interchangeably...

i just read that length of CP should be less then delay spread of channel model.
I am using Power line communication...
hi, could any one tell me wht should be the length of Cyclic Prefix(CP) in accordance to symbol/block length.
Is there any relation between or just any length is good?

I am stuck with one more problem:
when I would...
Iam trying to implement highest order digital filter of class chebyshev-I. while doing when I derive transfer function of chebyshev filter using POLY funciton of matlab. I found that it truncates the data hence stopping me to increase the order of filter. so could any body post the code which...
