    Abstract : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. READ MORE

  3. 2. LTE Uplink Modeling and Channel Estimation

    University essay from Datorteknik

    Author : Mohsin Niaz Ahmed; [2011]
    Keywords : LTE; Uplink; Channel Estimation; OFDMA; SC-FDMA;

    Abstract : This master thesis investigates the uplink transmition from User Equipment (UE) to base station in LET (Long Term Evolution) and channel estimation using pilot symbols with parameter defined in 3GPP (3rd Generation Partnership Project) specifications. The purpose of the thesis was to implement a simulator which can generate uplink signal as it is generated by UE. READ MORE
