Electrical Engineering)--University of the Philippines, Diliman. 520 ## $aOne measure of how well a particular adaptive antenna array configuration performs is its capability to reject interference signals in order to meet a certain performance goal. When the interference signals are wideband, the determination of the nulling capability of the antenna array is not as straightforward. In this research we attempt to quantify the maximum number of wideband interference signals that can be sufficiently nulled, under severe interference scenarios using a tapped delay line beamformer with a fixed number of antenna elements. This objective was accomplished through computer simulations where the performance of the tapped delay line beamformer is evaluated under various parameter settings and subjected to various interference scenarios. It is shown that increasing fractional bandwidth more taps are needed but to a certain limit. Also the results show that under severe interference scenarios, the maximum number of wideband interference signals than an array can sufficiently null with the minimal number of taps cannot improve beyond M-2. 650 ## $aElectric interference$xComputer simulation. 650 ## $aAntenna arrays$xComputer simulation. 650 ## $aDelay lines. 650 ## $aSignal detection. 905 ## $aFI 905 ## $aUP 852 ## $aUP$bDARCHIVES$hLG 995 2003 E64$iM38$rRegular Circulation$xUARD-10433T 852 ## $aUP$bDENG-II$hLG 995 2003 E64$iM38$pe2000000360$rRoom-Use Only$w2003$xE-491T 852 ## $aUP$bDARCHIVES$hLG 995 2003 E64$iM38$rRegular Circulation$xUARD-10433T 852 ## $aUP$bDENG-II$hLG 995 2003 E64$iM38$pe2000000360$rRoom-Use Only$w2003$xE-491T 842 ## $aThesis           Physical Location University of the Philippines Diliman Main Library: University Archives LG 995 2003 E64 / M38 Diliman: College of Engineering Library II LG 995 2003 E64 / M38           Digital Copy Not Available          Add to Book Cart  |   Download MARC
