【 摘 要 】

Massive Multiple Input Multiple Output (MIMO) is an evolving technology based on the principle of spatialmultiplexing which consists in using at the same time the same radio frequencies to send different signals. The severaltransmitting antennas from a base station can transmit different signals and several receiving antennas from a device can receiveand divide them simultaneously. Due to the physically difficult of installing antennas close to each other, standard MIMOnetworks generally limit four antenna-side transmitters and receivers for data transmission while it could be more. The studyaims to review the traditional MIMO different types as well as investigates the Signal-to-Noise Ratio (SNR) between Single InputSingle Output (SISO) and MIMO to ensure the best wireless connection functionality. In addition to that, a simple comparisonto distinguish between SISO, SIMO, MISO, and MIMO in term of capacity and data rate to provide an indication for the qualityof the wireless connection. The work's contribution is to illustrate technological benefits like MIMO, which boosts data speedsand increases the reliability of wireless networks. The outcome shows a SISO system would have a lower data rate thanother systems because it only has one antenna at the transmitter and receiver, whereas a MISO system would typically have agreater SNR than a SISO or SIMO system because it uses several transmit antennas. MIMO, however, took advantage of all thepositive characteristics and emerged as the best solution overall.
