OFDM

how I can find BER, PAPR and spectrum efficiency of SISO OFDM with USRP?

Maybe RTFM?  ("FM", of course, stands for Frequency Modulation, as I think this question is about radio ...)

The bit error rate would be calculated in the receiver based on whatever mechanism is used tfor data integrity checking (usually a crc that is reversed to recover erroneously decoded bits)

Find the Peak Power(P), find the Average Power(AP) Divide P by AP to get a Ratio(R)

The other XTLAs (eXtended Three Letter Acronyms) are; Single Input Single Output, Orthogonal Frequency Division Multiplexing and Universal Software Radio Peripheral.

can any one give the algorithm of OFDM in which we find the BER, PAPR and spectrum efficiency???

Thanks, JÞB, for allowing more of us to understand WTH the OP was trying to say ...

Hi sanjranikubra,

I have a couple question to clarify what you're asking about. Do you already have an OFDM signal and you're trying to figure out the BER, PAPR, and Spectrum Efficiency of that signal? Are you asking how to create a OFDM signal?

For calculating BER, PAPR, and spectrum efficiency, it's not any different for an OFDM signal. For example for BER, you're still going to be comparing the bits you're receiving with the bits you're sending and calculating the BER that way. 

When you ask for "the algorithm of OFDM in which we find the BER, PAPR and Spectrum Efficiency" I'm not sure what you mean by that.

hey

actually i was asking the implementation of OFDM ,FBMC and GFDM system using USRP, after that how to find its BER on different gain of antenna

[sanjranikubra]

can any one share the filter bank multi carrier and generalized frequency division VI?

Hi,

I found a LabVIEW OFDM example in the link below. As for the other VI's you're asking for, are these VI's you saw somewhere? I'm not finding any VI's with those names.
