Hello all,
I am currently doing an analysis of the OOB emissions of an LTE DL signal using the LTE DL Baseband verification example. However, when I look at the PSD via the spectrum analyzer module, the bandwidth of the LTE signal is limited to the Sampling Rate. I tried changing the sampling rate in the Dataflow Analysis template, nothing changed, then I changed the sampling rate of the carrier oszillator block but then the in-band bandwidth was extended. I want to keep the original bandwidth for example 5 Mhz (7.68 Mhz) but observe the signal power such as 30 Mhz away from the carrier frequency.
I've attached a pic of the PSD of the LTE DL signal. And thanks in advance.
Best regards,
Burak

P.S: I've attached the PDS of the upsampled LTE signal with the UpSampleEnv module using an upsampling factor of 20, polyphase filtering with an excessBW of 0.5.
