Hi everyone
I would like to implement key LTE baseband functions on Xilinx FPGA device, such FFT/IFFT functions. So I chose the Xilinx FFT core to do it. One big problem confusing me is that how to set the clock frequency of the FFT core so that it could meet the requirements of the LTE standard specifications??? I looked at the LTE specifications, in the case of LTE 10 MHz bandwidth, the FFT size is 1024 and sample rate is 15.36 Msps(million sample per second). So I am quite confused does that sample rate equal to the clock frequency, so I only need to set the FFT core clock frequency faster than 15.36 and that could meet the needs of LTE, am I correct?? or What else do I have to consider according to the LTE specification when I want to implement on FPGA???
So Please give me some suggestion if you know how to figure it out
Cheers
