New Trends in LTE

Title: New Trends in LTE.

Author        : Amr Fouad Abd-Allah Erfan
Collection   : M.Eng. Electric
Abstract:
This report is about good techniques can be used in 3G long term evolution mobile communication systems in Multiuser OFDM and the application of the smart antenna. Good techniques in Multiuser OFDM like adaptive technologies such as (adaptive modulation to increase the over all spectral efficiency anda simulation program which simulates the adaptive modulation and the performance can be improved by increasing the transmitting and receiving an rennas , proposed adaptive frequency hopping to increase received signal power) , comb spread carrier pattern to overcome partially the deep fading and proposed multiple transmitter cell which overcomes the shadowing problem. Beamforming technique which improves the performance and improves the signal to noise and interference ratio SNIRand a simulation program about a system with and without adaptive beamforming , also the smart antenna which increases the coverage and the capacity of the cellular mobile system.
