Explain Limit Signal Spectrum to Prevent Aliasing?
The sampling frequency should at least be two times that of the highest frequency in the incoming signal to avoid aliasing. This rate is generally known as the Nyquist limit.
With a maximum excess delay of and a chip duration of , the multipath components fall in delay bins. This means that we experience leakage of energy between chips and the channel i
