My environment: Matlab 2015a + NI USRP-2943R (X310+CBX)
Question:
In matlab support page http://cn.mathworks.com/hardware-support/usrp.html?s_tid=srchtitle, it says:
Supported Radios:
USRP2
USRP Networked Series (N210, N200)
USRP Bus Series (B200, B210*)
USRP X Series (X310*, X300*)
* SISO and 2x2 MIMO modes supported.
clearly 2x2 MIMO should be supported. However, I do NOT find any parameter that specifies which antenna port I access. By experiment I find that only RF 0 port can transmitting or receiving.
I want to know how I can access the other port. Thanks.

When a MIMO capable radio is selected as 'Platform' (i.e. B210, X300 or X310), you can select 'ChannelMapping' as described here:

Dear Ethem,
I have been trying to acquire signals from USRP X300 from both the receiver channels in simulink. It seems there is a problem in MATLAB 2020 version and above. It does not work while it works in MATLAB 2019. Has anyone encountered this problem
