Performance Evaluation of Implementing LCVM Beamformer for Cylindrical Antenna Array in Smart Array Antenna Applications

Array signal processing provides a capability for steering the mainbeam toward the direction of desired signals as well as for directing ideal nulls toward interference signals. Indeed, array signal processing techniques significantly enhance the accuracy and resolution of received signals by overcoming multipath fading and maximizing the SIR. This work has a major contribution to implementing the LCMV beamformer for the cylindrical antenna array for achieving high resolution and accuracy of received signals. The implementation of the LCMV beamforming technique for the cylindrical antenna array yields an excellent efficiency of 90.34%, as well as a high value of SIR of 2.257 (dB). The cylindrical antenna array has been implemented for transmitting data in the digital wireless communications using the IEEE 802.11x frames. In this scenario, the time domain evaluation of the cylindrical antenna array has verified that the maximum amplitude of voltage increases to 800 (volt) in the IEEE 802.11x frames.
