Is it possible to perform real-time low-pass filtering on the data received from the USRP X310 in Matlab

I do low-pass filtering on the received data from the X310, and find this step will slow down the processing speed.

Can implement filtering in the parallel way?

Can I do other demodulation steps parallelly in Matlab?

Thanks,

Alfred

Dunno, but you might want to look into the information presented in <High-Speed Data Transmit/Capture Using MATLAB and USRP> as well as the <Wireles Testbench>

Any data you receive from the USRP will be packetized and will suffer from variable time delay. It is not possible to perform real-time operations on this kind of data. The best you could hope for is "near real-time".
