Hi, I have to generate DVB-T and LTE signals using gnuradio companion. I'm in trouble because I don't know how to set some parameters in the OFDM modulator block.
LTE signal: transmission bandwith: 5MHz FFT size: 512 Cyclic prefix length: 128 occupied subcarriers:300 My questions concerning LTE signal are: 1) The number of occupied tones is the number of occupied subcarriers? 2)Which value should I set for the payload length? ----------------------------------------------------------------------------------------------------------- DVB-T signal: transmission bandwith: 5MHz FFT size: 8192 (8k) occupied carriers:6817 My question concerning DVB-T signal is: 1)Which value should I set for the Payload length and the Cyclic prefix length? In both cases of LTE and DVBT signals is it correct to set INPUT TYPE as "complex"? If someone could help me, I would be very thankful.
