In this paper, we study the effect of noisy links on the performance of distributed incremental least-mean-square (DILMS) algorithm for the case of Gaussian regressors. More specifically, we derive theoretical relations which explain how steady-state performance of DILMS algorithm (in terms of mean-square deviation (MSD), excess mean-square error (EMSE), and mean-square error (MSE)) is affected by noisy links. In our analysis, we use a spatial-temporal energy conservation argument to evaluate the steady-state performance of the individual nodes across the entire network. Our simulation results show that there is a good match between simulations and derived theoretical expressions. However, the important result is that unlike the ideal links case, the steady-state MSD, EMSE and MSE are not monotonically increasing functions of step size parameter when links are noisy. In addition, the optimal step size is found in a closed form for a special case which minimizes the steady-state values of MSD, EMSE, and MSE in each node. <\/jats:p>","DOI":"10.1155\/2011\/756067","type":"journal-article","created":{"date-parts":[[2011,2,20]],"date-time":"2011-02-20T19:33:01Z","timestamp":1298230381000},"page":"756067","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["Performance Analysis of Distributed Incremental LMS Algorithm with Noisy Links"],"prefix":"10.1177","volume":"7","author":[{"given":"Azam","family":"Khalili","sequence":"first","affiliation":[{"name":"Faculty of Electrical and Computer Engineering, University of Tabriz, Tabriz 51664, Iran"}]},{"given":"Mohammad Ali","family":"Tinati","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Computer Engineering, University of Tabriz, Tabriz 51664, Iran"}]},{"given":"Amir","family":"Rastegarnia","sequence":"additional","affiliation":[{"name":"Faculty of Electrical and Computer Engineering, University of Tabriz, Tabriz 51664, Iran"}]}],"member":"179","published-online":{"date-parts":[[2011,1,9]]},"reference":[{"first-page":"2033","volume-title":"Proceedings of IEEE Interntional Conference on Acoustics, Speech, and Signal Processing","author":"Estrin D.","key":"B1-2011-756067"},{"key":"B2-2011-756067","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-1286(01)00302-4"},{"key":"B3-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2006.1657815"},{"key":"B4-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2009.2022874"},{"key":"B5-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2005.863009"},{"key":"B6-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.874366"},{"key":"B7-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2005.847692"},{"key":"B8-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2005.855580"},{"first-page":"168","volume-title":"Proceedings of the International Conference on Information Processing in Sensor Networks","author":"Xiao L.","key":"B9-2011-756067"},{"key":"B10-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.896034"},{"key":"B11-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/ACSSC.2006.356622"},{"key":"B12-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2009.2025074"},{"key":"B13-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2008.917383"},{"key":"B14-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.913164"},{"key":"B15-2011-756067","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2010.02.019"},{"key":"B16-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.906734"},{"key":"B17-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.908943"},{"key":"B18-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2007.909006"},{"key":"B19-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2008.060687"},{"key":"B20-2011-756067","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2008.2007111"},{"key":"B21-2011-756067","first-page":"837","volume-title":"Proceedings of IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP '04)","volume":"3","author":"Chamberland J. -F."},{"volume-title":"Fundamentals of Adaptive Filtering","year":"2003","author":"Sayed A.
