Hi everyone I have a question about the dynamic range of the USRP 1. Let's say I have 2 input signals. The power of the one signal is such that it uses just about all the dynamic range of the ADC. How low can the second signal be in order for both to be detected when they reach the PC (after DDC and decimation)? Theoretically this should be around 72dB.
I did a simulation in Icarus where I fed a 6MHz wide chirp signal with a dynamic range of 72dB into the CORDIC module and looked at the output. The output signal only has a dynamic range of around 50dB. Does this mean that I did something wrong, or could we in fact lose that much dynamic range in the CORDIC? Thanks in advance.
