It is known that the desired signal steering vector error, the number of signal samples and the input signal to noise ratio (SNR) are crucial factors to the adaptive beamforming performance. In the presence of steering vector mismatch or lack of samp

The error in the look direction estimate can cause the mismatch between the actual and presumed steering vector. With this imprecise knowledge, the mainbeam is shifted leading to the self-null phenomenon of the desired signal and resulting in the per

This paper provides the capability of the direction of arrival (DOA) identification to determine which the estimated DOA belongs to the desired signal and to undesired signals. One of the well known subspace-based methods for finding directions is MU

To cancel interference signals that have fluctuated orientation of directions, the LCSS (Linear Constrained Sector Suppressed) approach is a null broadening beamforming based on the correlation matrix of the steering vectors on the predefined sector

In the scattering environment, multipath occurrence causes the angular spread (AS) around the direction of arrival (DOA) at the antenna array. Forming broad nulls at the interference directions in order to cancel all paths possible and keeping a main

Proceedings of the 2019 3rd International Conference on Graphics and Signal Processing.
Forming a broad null around the direction of interferences and keeping the main beam toward the desired direction is desirable to suppress interferences in the multipath environment. In this paper, a null broadening beamforming is proposed to enhance

Despite the advantages of direct sequence spread spectrum (DSSS) communications, intentional jamming or interference from other users reduces the robustness of the system to interference. Spreading the message by means of a pseudonoise sequence, DSSS
