I am implementing normal TDD type system where Tranmsitter and receivers switch between receiver and trasnmitter chain.
I am using NI-PXIe 1082 hence can control two USRPs from one graph/Panel.
How to insure :
1. Rx switches from trasmittion to reception
2. Tx switches from reception to transmission
3. Tx switches from transmission to reception
4. Rx switches from reception to transmission
..
Each steps are progressively in time domain.
I want to switch in two different cases: fixed time dwell and fixed packet transmitted/received.
Any example I can look in? Key points to change?
