Sampling Rate modifying in Deploying an Application to an FPGA

[erifirst]

Hello,

I am studying the performance of the OFDM(100MHz BW needed) using NI USRP 2954R. For this, I need the 100 MHz bandwidth.

OFDM Parameter values that I calculated are belows

=========================================

 FFT_Size =  2048 x 5 = 10240

CP Length = 128 x 5 = 640

Sampling rate = 30.72MHz x 5 = 153.6 MHz

Used Sub carrier = 6000

Occupied_BW = 15000 x 1200 x 5 = 90MHz

Is it Possible with USRP 2954R(160MHz BW) ?

=========================================

 I can't modify even sampling rate in EXERCISE 5 - Deploying an Application to an FPGA Example......  I have been doing for 4 days.....

Any help is greatly appreciated.

Thanks!

Sorry , FFT_Size is 8192

Hello!

Are you trying to just implement OFDM, or are you trying to implement other functionality in the PHY? Also, were you working with the Multirate Diagram?

This should be possible with the 2954 since each daughter board is capable of 160 MHz BW, and the FPGA should be clockable at that speed.

What issues have you been running into so far?

Cheers,
