Basics of MIMO Radio Systems

April 4, 2019, 11:57 am

This article introduces the rationale and techniques involved with MIMO (Multiple-Input, Multiple Output) based communication systems. The communication impairments due to multipath channels are discussed in order to provide the base motivation for the application of the MIMO technique and in particular, the use of OFDM (Orthogonal Frequency Division Multiplexing) and spatial multiplexing for equalizing broadband wireless channels with non-selective fading.
