Need Help for OFDM upsamplin and Downsampling
Dear AOa;
Need your HELP i am using raspberry Pi As OFDM modulator and Demodulator. I have made a model. It is working fine when it is in Baseband as i am Upsampling it by factor of 20 and Downsampling it by a factor of 20.then at receiver i am receiving errors upto BER 0.5. in simulink model. kindly help.
I am generating data using Bernoulli generator with following Specs.
a.sample time= 1/1800
b.Sample per frame=48
I am using PAM for modulation
Using 64 carrier in IFFT
48 Data symbol
15 Gaurd carrier
1 DC carrier
Then I am Upsampling it by factor of 2 and then 10 total 20 and using FIR filter for Interpolation
at Reciever
I am Downsampling it by a factor of 2 10 and then 2 and using FIR filter for decimation
.But at receiveing error.
I have tried to introduce a delay but it is not working using Delay block
