I would like to know if I need to Up convert my signal from Baseband to Operating frequency or just need to input my Baseband Signal to phased.array radiator object??? if I upconvert my signal and then down convert the output signal. Then it gives me wrong results of Doppler shift.

Hi Waseem, you just need to input your baseband signal to the radiator object.
If you look at the phased.Radiator object, you will notice an 'OperatingFrequency' property. The underlying assumption of the phased.Radiator object is that your signal data is the baseband signal which modulates a carrier frequency.

Hi Waseem - thanks for providing this information, now I understand what you are doing.
It seems that the phased.Radiator does not provide any support for propagating unmodulated signals. Therefore, I think that the phased.Radiator will only work with your baseband signal, with the OperatingFrequency property set to the final carrier frequency of the transmitted signal.
