In view of the significance of the array manifold in array processing and array
communications, the role of differential geometry as an analytical tool cannot be …

This paper proposes a direction-of-arrival (DOA)-based beamforming approach for multi-cell
massive multiple-input multiple-output systems with uniform rectangular arrays (URAs). The …

With requirements of spiraling data rates and limited spectrum availability, there is an
increased interest in mm-wave beamformer-based communications for 5G. For upcoming …

Recently the effect of the angular spread caused by locally scattered signals in the vicinity of
the mobile has received considerable attention. This paper proposes the Extended Array …

This article presents an approach for the synthesis of time-modulated circular array patterns
with specified null width constraints. The time-modulated circular antenna arrays with …

Multipath fading effects and co-channel interference are the main limitations facing wireless
communication systems. The problem to enhance the capacity of a code-division multiple …

With single-input single-output (SISO) SAR systems, employing a single transmitter and
receiver beam, there exists a high resolution, wide swath contradiction. However, by using …

In orthogonal frequency division multiplexing (OFDM) based cellular systems, co-channel
interference (CCI) from adjacent interfering base stations (BSs) operating and coexisting …

This thesis discusses two important subjects in multi-user wireless communication systems,
radio resource scheduler (RRS) and smart antenna. RRS optimizes the available resources …

Wireless communication technologies bring numerous benefits for smart grid applications
including lower cost, more flexibility, easier installation, etc. In this paper, the performance of …
