1.  Adaptive Array Behavior with Periodic Envelope Modulated Interference Al-Ruwais, A.S.; Compton, R.T.; Aerospace and Electronic Systems, IEEE Transactions on Volume AES-21,  Issue 6,  Nov. 1985 Page(s):757 - 766 Digital Object Identifier 10.1109/TAES.1985.310660 Summary: A method is presented for determining the effects of envelope modulated interference on a least mean square (LMS) adaptive array. The interference is assumed to have periodic envelope modulation with a bandwidth that is small compared with the carrie.....

2.  Adaptive Array Behavior with Periodic Phase Modulated Interference Al-Ruwais, A.S.; Compton, R.T.; Aerospace and Electronic Systems, IEEE Transactions on Volume AES-23,  Issue 5,  Sept. 1987 Page(s):602 - 611 Digital Object Identifier 10.1109/TAES.1987.310853 Summary: We consider a least mean square (LMS) adaptive array [1] receiving a phase modulated interference signal. The phase modulation is assumed to be periodic and to have finite bandwidth. Under these assumptions, we determine the time-varying array weight.....

3.  Adaptive Array Behavior with Sinusoidal Envelope Modulated Interference Al-Ruwais, A.S.; Compton, R.T.; Aerospace and Electronic Systems, IEEE Transactions on Volume AES-19,  Issue 5,  Sept. 1983 Page(s):677 - 687 Digital Object Identifier 10.1109/TAES.1983.309370 Summary: The behavior of a LMS (least mean square) adaptive array with modulated interference is described. An interference signal with sinusoidal, double-sideband, suppressed-carrier modulation is assumed. It is shown that such interference causes the array .....

4.  Measurements of RF radiation near MW and SW radio broadcast stations Al-Ruwais, A.S.; Broadcasting, IEEE Transactions on Volume 44,  Issue 4,  Dec. 1998 Page(s):470 - 477 Digital Object Identifier 10.1109/11.735910 Summary: Far field measurements of electric and magnetic fields in an area surrounding the MW and SW broadcast stations in Riyadh, Saudi Arabia are presented. Values of the electric fields contribution from each of the MW and SW stations separately are estima..... AbstractPlus | Full Text: PDF(496 KB)    IEEE JNL Rights and Permissions

5.  Subspace-based approaches for narrowband interference suppression in DS spread spectrum systems ALshebeili, S.A.; Al-Qurainy, A.M.; Al-Ruwais, A.S.; Signal Processing Proceedings, 1998. ICSP '98. 1998 Fourth International Conference on 12-16 Oct. 1998 Page(s):389 - 392 vol.1 Digital Object Identifier 10.1109/ICOSP.1998.770233 Summary: In this paper, a new method utilizing a subspace-based interpolation error filter for narrowband (NB) interference suppression in direct sequence spread spectrum (DSSS) systems is presented. The performance of DSSS communication systems is studied wh..... AbstractPlus | Full Text: PDF(264 KB)    IEEE CNF Rights and Permissions
