Hi all
for a specific project I have to stimate how much ram do I need for OFDM modulation and demodulation (WiMax) to impliment it on FPGA chip, however I do not know how I can estimate it.
I have this information:
FFT : 1024
BW: 10Mhz
Symbol number: 46:
1- Uplink: 15=12data+3 parity & bit per symbol: 560
2-Downlink: 31 = 28data+3parity & 720 bit per symbol
well, i do not know how you calculate it but i want to tell you that the FFT must be 2^n so that if you used 1026 then u must use the DFT instead. I see in your question above the FFT = 1026. I think miss typed it.
