Channel estimation in 5G wireless communication system in matlab

The demands of multimedia services from mobile user equipment (UE) for achieving high
data rate, high capacity and reliable communication in modern mobile wireless systems are
continually ever-growing. As a consequence, several technologies, such as the Universal
Mobile Telecommunications System (UMTS) and the 3rd Generation Partnership Project
(3GPP), have been used to meet these challenges. 5G communication is designed for all these
requirements with extra reliability, capacity and speed. However, due to the channel fading
and the Doppler shifts caused by user mobility, a common problem in wireless systems,
additional technologies are needed to combat multipath propagation fading and Doppler
shifts. Time-variant channel estimation is one such crucial technique used to improve the
performance of the modern wireless systems with Doppler spread and multipath spread.
