why is the size of fft not equal to the num of sub channels?
Tom Barak
49:34
after the IFFT for each subcarrier channel - we get N signals for N subchannels. after that we sum them?

SC-FDM is just for upstream is due to power consumption constraint? downstream is regular OFDM?
Gregory Kovelman

Ok, thanks
יעקב שטיין

each of the N complex values is multiplied by e^inwt and then all of these are added - which is exactly what the FFT does! the FFT does the multiplication by e^iwt and the sum. OK?

in 20MHz BW, why do we use only 1200 SC's +10
עידן הורן
01:11:11
% guard band and not more SC's?
יעקב שטיין
01:11:49
4G decided to leave large guard bands in order to reduce the frequency sync requirements of neighboring cells
