Design and analysis of multiple-input multiple output (MIMO) system for research purposes

Annotation: Systems with multiple input and multiple output (MIMO) play a key role in modern wireless communication devices. MIMO are used in wireless networks to increase channel throughput and transmission reliability. The implementation of the MIMO system will speed up research in the field of improving communication systems. In this article, we present a system-level analysis of a block-level analog RF receiver in a MIMO system in accordance with the performance requirements described in the 3GPP Long-Term Evolution standard. An analytical study of the analog receiving part was carried out. The results show that the proposed system architecture satisfies the given requirements with a good margin. Numerical simulation of the operation of the 44 MIMO system in the line-of-sight environments was performed. Taking into account the influence of only the noise of the receiver, a curve is obtained that determines the dependence of the error probability on the distance between the transmitter and receiver. Using this curve, it is possible to determine the distance corresponding to a given error probability for given aperture sizes of the transmitting and receiving arrays.
