Abstract
The major requirements of fifth-generation (5G) cellular networks and further are low latency and great speed of data transmission. One such way to fulfill these requirements is to make use of 5G enabling technology called Millimeter-wave (mmWave) communication. The cellular systems relying on this technology can function with higher data transfer rate up to gbps due to the availability of large band width. A very high transceiver intricacy is required exorbitantly in the case of conventional MIMO methods whereas digital precoding/conjoining is generally accomplished at baseband with single radio frequency (RF) sequence and a single ADC per antenna in case of traditional MIMO systems. So an all-digital processing approach is prohibitive owing to the high price and power depletion of RF chains and ADCs at frequencies of mmWave. This appraisal primarily aims at offering a complete analysis of channel approximation techniques accompanied with various diversified millimeter wave scheme. Consequently, in terms of their corresponding aids and inadequacies a comparison is also provided among prevailing resolutions.
