Convert dBm/Hz to dBW/ 100 Hz?

You can always convert from dBm to dBW by subtracting 30dB. That's because dBm is a power relative to 1mW and dBW is the power relative to 1W -- and 1mW / 1W = 1/1000, which is -30dB. Any time you ...

Let's to the step by step. $dB/Hz$ is a unit for power spectral density so it's a function of a power/energy and bandwidth. When converting from $dBm/Hz$ to $dBW/Hz$ you change the reference from $1mW$...

Does the data rate of ofdm depends on number of subcarriers

According to my understanding, the subcarriers spacing Δf=B/N so increasing the number of subcarriers B will decrease the subcarrier spacing and hence increase the achieved data rate at the expense of ...
