A particular communication system I came across defines chip time to be 0.57 ns and consequently chip rate is 1760 MHz.
The transmission bandwidth is 2.16 GHz.
I am wondering, do we suspect to have aliasing? Given the fact that the chip rate is smaller than the bandwidth of transmission? In other words shouldnt the sampling rate (which I assume is 1760 MHz) be at least greater than 2.16 GHz so as to prevent aliasing?
