Abstract

Abstract:

MIMO is a key technology which widely used in the next generation of mobile communication systems. Without an increase in the bandwidth of communication it has multiplied to increase system capacity and spectrum utilization. There are many MIMO technologies motions having submitted in 3GPP. This paper introduced MIMO and its two applied technologies, namely PARC and D-TxAA, and has given simulation result by contrast.

Key words: multiple-input multiple-output, PARC, D-TxAA, simulation, 3GPP
