Hi All,
I am simulating ofdm signal and plotting its ber with and without clipping. I wonder if i'm getting it right. I get bit errors after clipping when I add awgn noise to the signal also. otheriwse simulating only clipping (baseband ofdm ) doesnt return me any error. wehn i add awgn noise...
Hi All,
I'm really in trouble because of this awgn. I am trying to add noise awgn to oversampled ofdm signal. my signal is oversampled 20 times and modulated on a high frequency carrier. After applying band pass filter I have tried to do this
SNR = EbNo + 10*log10(k) - 10*log10(upsamp)...
phase and amplitude both is changing. I'm using 40th order FIR filter. I think it is giving a delay of 20 samples, bcz of that delay the constellation is changing. I 'm looking for SOLUTION TO handle that delay.
Hi all,
I have to use fir filter for low pass filtering of the signal. when I use it, the constellation diagram after demodulation is very different from the original before modulation. It is in the round shape. When i use decimate function to low pass filter and downsample, it is different...
Hi,
I am trying to undertsand OFDMA uplink transmission. Can someone explain me, how it works, if there are multiple users at different locations, how can it be used ofdma,,,,
plz i need help regarding this,,,
Thanks
