+# Channel MIMO plugins
+
+These channels can process multiple synchronous streams from or to a MIMO device supported by a [Device MIMO plugin](./Device-MIMO-plugins-(Multiple-In-Multiple-Out))
+
+## Simple Interferometer plugin
+
+This MIMO reception only (MI) plugin can be used to study phase difference between two coherent streams. It must be connected to a device that exposes at least two input streams and will connect to streams 0 and 1 as channels A and B respectively. The user interface is described [here](https://github.com/f4exb/sdrangel/tree/master/plugins/channelmimo/interferometer/readme.md)
+
+## Beam Steering Continuous Wave plugin
+
+This MIMO transmission only (MO) plugin can be used to drive a 2 channel MO device in order to produce a continuous wave signal (CW) with a control of hte phase between the two streams. When the MO device is connected to a two antenna system the resulting beam can be steered in direction using the phase difference. Control is made directly in angle units. The user interface is described [here](https://github.com/f4exb/sdrangel/tree/master/plugins/channelmimo/beamsteeringcwmod/readme.md)
