I am sending a repeating BPSK modulated PN sequence signal from a USRP x310 transmitter. I am receiving the sequence with another USRP x310. Both are attached to an octoclock. Is there a way to get the global time when the receiver starts writing to the file sink?
Here is a look at the receiver block diagram:
Currently, I can use the file metadata sink to get the time it starts writing (starting at 0 sec) and subsequent writes after a number of samples. But it does not give the global time. I eventually want to use this global time measurement to calculate the time difference of arrival at multiple receivers.
