## 1 Introduction  
With the rise in advanced technologies, there is a maximum possibility that the future intelligent hospitals will enhance the quality of medical services, such as remote surgery, diagnosis, instant sharing of reports to the best experts in the world, and health monitoring. In recent years, 4G network has been utilized to support the smart health care system. However, it has not developed all over the globe [1]. The implementation and regularization of 5G are taking place all over the world. The 5G communication system is taking the level of communication to the next standard by increasing the speed, efficiency, safety, and latency [2]. In the upcoming years, 5G networks will enhance their service in different sectors such as manufacture, education, wellness care, transportation, and so on. Hence, the upcoming advanced network should carry through the demands of different sectors, and the demands of these sectors are different from each other. The advanced radio network design, new infrastructure, towers, picocell, and microcell are considered a huge challenge while minimizing the project's cost. Hence, the 5G standard will be a combination of current and future developments [3]. The integration of 5G, the Internetof Things (IoT), and smart hospitals can improve the quality of medical services. The IoT machines can continuously monitor the conditions of the patient and analyse the data. However, in the present scenario, the use of IoT and wearable devices is less due to the low spectrum, speed, and bandwidth. Hence, it is important to explore 5G advanced waveforms with low leakage, high data rate, and high bandwidth capabilities [4]. In several years, the use of technologies has improved the measures of health monitoring at a modest scale. It is expected that advanced technologies will further enhance the performance of smart hospitals. Advanced technologies such as the Internet of Things (IoT); advanced waveforms, including non-orthogonal multiple access (NOMA), millimetre wave (mm-wave), filter bank multi-carrier (FBMC), and cognitive radio will play a key role in healthcare [5]. In the present scenario, healthcare systems are facing enormous pressure to meet the demands of patients. With the increase in the population, it is becoming difficult for conventional hospitals to execute their services efficiently for the mass population. It is seen that the conventional hospitals are being digitized, but still, the hospitals are not completely digitized. It is important to enhance the infrastructure in smart hospitals and implement an advanced healthcare system empowered by essential advanced technologies, which can deliver an advanced facility that was not accessible previously [6]. Currently, orthogonal frequency division multiplying (OFDM) is employed in the 4G framework. OFDM suffers from 11% spectrum loss due to the use of cyclic prefix (CP). There are several other disadvantages due to which OFDM may not be considered for the upcoming 5G radio network [7]. Hence, in recent years, more advanced waveform techniques are being researched. FBMC is a technology that has grabbed the attention of researchers due to its characteristics, such as spectral efficiency and high data rate. In recent studies, it has been seen that FBMC is compatible with massive MIMO. The structure of FBMC consists of a group of filters, FFTs and IFFTs. One of the important parameters affecting the performance of Smart hospitals is the fast transmission of medical data and images. The medical scans and reports consist of large amounts of memory. Hence, if the data speed and bandwidth are low, it will create a delay in getting the medical expert's opinion. This further leads to a delay in the treatment of the medical patient. Therefore, to transmit a large number of medical files, the speed and bandwidth should be high. However, the transfer of medical files and reports requires a high data rate and high network bandwidth, which is not guaranteed by the current fourth-generation standard (4G) [8].
