Microwaves are used to communicate with satellite and terrestrial communication networks. But as microwaves pass through the Earth’s atmosphere, the oxygen gas absorbs microwave. In this 5G era, when the whole world is moving towards high data-rates and reliable communications, this absorption affects the data transmission in integrated satellite/terrestrial communication (ISTC) systems, which leads to degradation of the system performance. However, the superior data-rates and better transmission reliability requirements of modern and future (5G and beyond) practical wireless communication systems may easily be acquired by using the multiple input multiple output (MIMO) techniques. The authors investigate MIMO diversity results by considering the effect of varying signal-to-noise ratio (SNR) value on key performance indicators block error rate (BLER), throughput and error vector magnitude (EVM). The paper envisages that higher order MIMO configuration is capable of providing reliable signal transmission and higher data rates both. MIMO 8×1 provides 5, 20 and 42.5 times improved performance to BLER; 5.26 per cent, 25 per cent and 81.82 per cent in throughput; and 10.34 per cent, 23.07 per cent and 28 per cent in EVM calculations as comparable to MIMO 4×1, MIMO 2×1 and SISO 1×1, respectively at a moderate SNR value of 15 dB. The authors also give a new concept of multi-cellular layers based mobile communication network, useful for future smart cities.
