synchronous and asynchronous cdma
the reverse link is difference. For synchronous cdma, the signals from different MS arrive at BS at the same time which reduces the complex of algorithm in BS.
dvb-t baseband signal bandwidth
use ur QAM16 datas to modulate N cos2*pi*f(i)*t+jsin2*pi*f(i)*t and make sure the N sinusoid wave orthogonal. do fft and plot the magnitude then u will see u want to see:)
