Abstract
Owing to the higher frequency, bigger network capacity, and reduced latency, fifth generation mobile communication (5G) has garnered a lot of interest with the rapid advancement of technology. It incorporates a variety of technologies, including “millimeter-wave (mmWave) transmission and massive Multiple-Input Multiple-Output (MIMO)”. The existing digital precoding is too expensive to implement in mmWave communication systems. As a result, hybrid precoding, which mixes digital and analog precoding, is a superior option. It is generally built on one of two types of structures: “fully connected and sub-connected. The fully connected structure” has been intensively explored in the academic community because it can approach the theoretical ideal spectrum efficiency. The high antenna size, on the other hand, complicates the necessity for a low-complexity "channel estimation and hybrid precoding design". Hybrid precoding, in specific, may necessitate “matrix operations on a scale of antenna size”, which is often significant in mmWave transmission. In order to learn more about the latest developments in mmWave large MIMO communication systems, this paper aims to undergo a critical review on channel estimation and hybrid precoding in mmWave massive MIMO communication systems. This review evaluates the different algorithms to be implemented for both “channel estimation and hybrid pre-coding in communication systems”. In addition, the performance measures concentrated in each contribution are observed and categorized. Finally, the conventional strategies will relieve the existing research gaps and challenges with new research directions to be used for the future professionals to maintain the “channel estimation and hybrid pre-coding of mmWave massive MIMO system” at a good level.
