Channel estimation algorithms for hybrid antenna arrays:performance and complexity

Autor: Tapio, V. (Visa), Aminu, M. U. (Mubarak Umar), Lehtomäki, J. (Janne), Juntti, M. (Markku)

At the millimeter wave and higher frequency bands the radio channel can often be expressed as a linear combination of a small number of scattering clusters. Hence, the number of angles of arrivals with significant components is limited. Due to severe

Modified handover decision algorithm in long term evolution advanced network

Autor: A. S. Sada, A. M. S. Tekanyi, Y. A. Maiwada, A. U. Mubarak, Aliyu D. Usman, Z. M. Abdullahi

Heterogeneous deployment of access points is considered as a promising technique for improved network performance in 4G networks. While the heterogeneity of the network results in reduced cell sizes thereby improving network coverage, inter-cell hand

Beamforming and transceiver HW design for THz band

Autor: Aminu, M. U. (Mubarak Umar), Tervo, O. (Oskari), Lehtomäki, J. (Janne), Juntti, M. (Markku)

The new spectrum available in the millimeter-wave (mmWave) and Terahertz (THz) bands is a promising frontier for the future wireless communications. Propagation characteristics at these frequencies imply that highly directional transmissions should b
