Wireless-Powered Relaying Communication based on MIMO-OFDM: A Comprehensive Survey

As a direct and immediate result of the phenomenal expansion that has taken place as a direct result of the introduction of mobile data and digital assistants, there is an urgent need for increased channel capacity across all aspects of cellular and wireless telephony. This need can be summarized as follows: The most crucial purpose of the wireless networking technologies that are accessible today is to provide a connection that has a high data rate and is uninterrupted while yet maintaining a decent quality of service. This is the case even though the technologies are wireless. The multiple-input, multiple-output (MIMO) communications technology, which provides increased connection reliability and higher spectrum efficiency by making use of antenna spectral efficiency, seems to satisfy these requirements. In order to build up a MIMO-OFDM system (Orthogonal Frequency-Division Multiplexing), it is necessary for both the receiver and the broadcaster to combine OFDM with array antennas. This is done at both the receiver and the broadcaster. Because of this, it is possible to increase both the dependability of the bandwidth and the efficiency of the multipath signal transmission. Additionally, the efficiency of the multipath signal transmission may also be enhanced. This technology not only provides communication that is trustworthy, but it also provides communication that is comprehensive throughout its many application domains. Not only does the paper provide a concise explanation of MIMO and OFDM theories, but it also provides an in-depth examination of the benefits and drawbacks associated with technical breakthroughs such as these. After first presenting a proposal for a suggested system, the study then moves on to the next step, which is a more in-depth analysis of the operational concept.
