To answer your questions:
- Yes, you can import the IQ data into your workspace and combine it with the signal at the existing workspace. To do this, you would need to load the IQ data into MATLAB using the "load" function, which will create a variable containing the IQ data. Then, you can use MATLAB functions to combine the two signals, such as adding or multiplying the signals depending on what you want to achieve.
- Yes, there are parameters you need to take into account when combining the IQ data with the existing signal. Some of the parameters to consider are the sampling rate, the number of samples, and the center frequency of the signals. If these parameters do not match between the two signals, you may need to resample one of the signals to match the other signal's parameters before combining them. Additionally, you need to make sure that the IQ data represents a signal that is within the bandwidth of the existing signal.
Finally, I would like to clarify one point you mentioned in your question. You mentioned importing a BPSK signal at 1.01 GHz frequency to combine with a QPSK signal at 1 GHz frequency. However, BPSK and QPSK are modulation schemes, not frequencies. It is important to understand the difference between the modulation scheme and the frequency of the signal. If you want to combine two signals with different center frequencies, you would need to perform frequency shifting on one of the signals before combining them.
