Hi everyone,
Can someone please tell me how we can calculate the OFDM symbol efficiency in OFDM modulator .osd file?
Also why in the OFDM transmitter side, the quadrature modulator has the frequency of 7.5 GHz?
Hello Ina,
The 7.5GHz is the carries frequency used to carry the QAM/OFDM modulated signal. Users can set their own carrier frequency.
Typically spectral efficiency of a modulation scheme is calculated based how many bits/s/Hz. However, users need to consider the number of bits/symbol and number of subcarriers, actual bandwidth used by the modulated signal, etc…
A very good reference can be found at
