Abstract

The following are methods for transmitting multiple signals in MIMO systems. Such as multiplexing, separation of the signal for reception and transmission, adaptive transmission, and also shows how they can increase. The main method of increasing bandwidth in MIMO systems is multiplexing, that is, the parallel transmission of several streams of information from different antennas. Separate cases of MIMO are transmission systems, where one receiver or transmitter uses one antenna. These are called Multiple-input single-output (MISO) and Single-input multiple-output (SIMO) systems. Considered work from the point of view of 802.11 Wi-Fi, though, these methods are also used in other wireless standards (LTE, 802.16 WiMAX).

Keywords: Multiple-input multiple-output (MIMO), multiplexing, adaptive transmission, beamforming, Wi-Fi.
