Energy as mean of absolutes of data samples
Normally, we find the energy of a given signal as $\sum{{x_n}^2}$. But, what if I compute, energy as $\sum{|x_n|}$. In the latter case, if I want energy in dB, which formula should I use - $10\log_{10}...

I have a doubt regarding FFT size in 5G NR 60 MHz Bandwidth
maximum RBs for 60MHz with SCS = 30 kHz is defined to be 162 RBs, so NSubcarriers is 162 x 12 = 1944, 1944 < 2048. Then NFFT size for 60 MHz bandwidth with SCS = 30 kHz should be 2048 instead of ...
