A SURVEY PAPER ON LTE TRANSMISSION SCHEME

LTE was proposed in 2004 Toronto conference to fulfill the requirement of achieving higher speed and lower packets latency in UMTS 3G systems. LTE which is abbreviated as long term evolution is an basically a transmission mode of providing the communication channel/communication link between the mobile portable device's connected with each other to establish the connection between the two. LTE is composed of many new technologies compared with the previous generation of cellular systems. These new technologies are used to generate more efficiency with regards to spectrum and higher data rates as expected by designers. The currently agreed LTE architecture adopts a flat architecture, inheriting four functional elements named as Evolved Radio Access Network, User Equipment (UE) and hosts the physical layer (PHY), Medium Access Control (MAC), Radio Link Control (RLC), and Packet Data Control Protocol (PDCP) layers, Serving Gateway (SGW) and Mobility Management Entity. To do this work it has various numerous number of techniques through which it establish the link between the two. The technologies were named as OFDM, MIMO, and FDMA, SC-FDMA and so on. as it keep and maintains accuracy while providing the medium cascade to perform the task as it make use of TDD,FDD,QAM as multiplexing technologies.
