Performance Analysis of Random Access Protocol in Crowded LTE Network over Nakagami Fading Channel

Abstract

The Massive Multiple input multiple output (MIMO) technology has a boundless potential to accomplish the fastgrowing data traffic in wireless network. Massive MIMO attains excellent spectral efficiency by spatial multiplexing of many tens of User equipment (UE). These gains are only realized by practicing if several UE's can connect effectively to the wireless network than today. As the no. of UE's continuously intensifying, while each & every UE irregularly accesses the network, there by random access protocol plays vital role in sharing the restricted no. of pilots among the connected UE's. In this paper, traditional techniques for pilot allocation in MIMO based network and random access protocol techniques used for pilot allocation inovercrowded Long term evolution (LTE) network and resolved as well as unresolved collisions while assigning pilot.
