Improving the performance of LTE technology by using MIMO and OFDM
(Проблеми телекомунікацій, 2011) Al-Janabi, H. D.; Vadia, Z.
In this paper we consider the ability to increase the LTE performance using MIMO systems and frequency diversity methods like as OFDMA and SC-FDMA. The effect of using the adaptive modulation in time and frequency domain by taking advantage MIMO and OFDMA and SC-FDMA in LTE technology is investigated.
Model to improve required qualities of transmission rate in wimax technology downlink
(НУ ЛП, 2013) Al-Janabi, H. D.; Al-Dulaimi, A. M.; Abed, A. H.
The given work presents mathematical model of sub-channels distribution using various kinds of objective functions in offered model is directed to allocation of minimum data rate transmission of every user station. Subcarrier frequency is primary building block of OFDM method that using to distribute sub-channel for users as in this work used submode OFDMA FUSC Full Usage of Subcarriers, the element of frequency resources, called the sub-channel.
