    Comparative analysis of using transmission and receiving diversity methods in WiMAX technology
    (ХНУРЭ, 2009) Loshakov, V.; Vadia, Z.; Hasan, A.
    WiMAX o f 802.16e standard is a very promising wireless technology which can support transmission rate about 45Mbit/sec. By adding the fast mobility with the high bit rate WiMAX 802.16e is considered the future o f wireless networks. Because mobile WiMAX is not line o f sight technology it makes the multifading channels interference a very severe problem which challenges the WiMAX performance ability.

    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.
