MIMO Communications

Abstract

Multiple-input multiple-output (MIMO) communication technology has proved itself as a widely used technology nowadays. MIMO can be generally referred to as a communication channel which has multiple numbers of transmitters and receivers of antenna which directly affects the communication's performance. These days MIMO communication technologies are used in various technologies such as long-term evolution (LTE) and Wi-Fi. In this article, we discuss the different terminologies related to the MIMO communication systems such as its narrowband model characteristics, MIMO channel capacity and decomposition of the channel, various types of its diversity gain based methodologies & also its space-time modulation and coding techniques. This paper provides a brief summary of various multiple-input multiple-output technologies emphasizing its various characteristics.
