We recall the basics of digital MIMO processing for polarization-division demultiplexing and mode-division demultiplexing and draw some similarities/differences with radio applications. We illustrate the impact of nonlinearities on the mitigation of mode coupling and discuss the challenges of mode-dependent gain in a multimode optical amplifier.
