frequency shifting of band limited signal

Asked by saima on 19 May 2013

Hello,

I have a nearly band limited data set. The band is centered at 7MHz. But I need to shift this band. How can I perform this shifting in both direction using matlab?

I multiplied a complex exponential in time domain to accomplish this shifting. But distortion in the spectrum was resulted. Any possible solution?
