In this work we present a new idea of sidelobe suppression applicable for cognitive users on transmitter and receiver sides. In case of spectrum sharing with the primary users by suppressing the side-lobes at the transmitter and receiver side, the cognitive users will be able to increase the throughput without cooperating the permissible interference temperature limit of the license spectrum. We suggest two generalized sidelobe cancellers (GSCs) that operate in parallel. The first GSC planned to attain the two conflicting objective at the same moment: firstly maximize the cognitive users self throughput; secondly minimize the interference generated by cognitive users at each primary receiver. The second GSC generates two main beams at the positions of the highest amplitude sidelobes of the first one. The values of main beams are equal to the two sidelobe peaks. The subtraction of the outputs of the two GSCs, results in the suppression of the highest pair of sidelobes. This process is repeated iteratively to result in an adaptive algorithm. Simulation results are there to provide the effectiveness of the proposed algorithm. <\/jats:p>","DOI":"10.1155\/2014\/418192","type":"journal-article","created":{"date-parts":[[2014,6,4]],"date-time":"2014-06-04T21:05:39Z","timestamp":1401915939000},"page":"418192","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Spectrum Sharing in Cognitive Radio Using GSC with Suppressed Sidelobes"],"prefix":"10.1177","volume":"10","author":[{"given":"Syed Azmat","family":"Hussain","sequence":"first","affiliation":[{"name":"School of Engineering & Applied Sciences (SEAS), Isra University, Islamabad Campus, Islamabad 44000, Pakistan"}]},{"given":"Aqdas Naveed","family":"Malik","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, IIU, H-10, Islamabad 44000, Pakistan"}]},{"given":"Zafar Ullah","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, IIU, H-10, Islamabad 44000, Pakistan"}]},{"given":"Ijaz Mansoor","family":"Qureshi","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, Air University, Islamabad 44000, Pakistan"}]}],"member":"179","published-online":{"date-parts":[[2014,6,4]]},"reference":[{"key":"B1-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/49.730452"},{"key":"B2-2014-418192","first-page":"987","volume-title":"Proceedings of the Annual Allerton Conference on Communication, Control, and Computing","author":"Bengtsson M."},{"key":"B3-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/WSA.2008.4475534"},{"key":"B4-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/TAP.1976.1141412"},{"key":"B5-2014-418192","volume-title":"Handbook of Antennas in Wireless Communications","author":"Bengtsson M.","year":"2001"},{"key":"B6-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/98.788210"},{"key":"B7-2014-418192","unstructured":"Mitola J.Cognitive radio: an integrated agent architecture for software define radio [Ph.D. thesis]2000Stockholm, SwedenRoyal Institute of Technology (KTH)"},{"key":"B8-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2004.839380"},{"key":"B9-2014-418192","first-page":"103","volume-title":"Proceedings of the 1st European Wireless Technology Conference (EuWiT \u203208)","author":"Lian X."},{"key":"B10-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/GLOCOM.2007.564"},{"issue":"2","key":"B11-2014-418192","first-page":"41","volume":"9","author":"Suleesathira R.","year":"2013","journal-title":"WSEAS Transactions on Signal Processing"},{"key":"B12-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/MVT.2009.934672"},{"key":"B17-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/JSTSP.2010.2053016"},{"key":"B13-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2013.042313.120752"},{"key":"B14-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/CROWNCOM.2008.4562465"},{"key":"B15-2014-418192","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2010.0385"},{"key":"B16-2014-418192","doi-asserted-by":"publisher","DOI":"10.1016\/j.sigpro.2012.10.021"},{"key":"B18-2014-418192","first-page":"1661","volume-title":"Proceedings of the 20th International Conference on Acoustics, Speech, and Signal Processing","volume":"3","author":"Anu Y."},{"key":"B19-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/78.330367"},{"key":"B20-2014-418192","doi-asserted-by":"publisher","DOI":"10.1155\/2014\/582397"},{"key":"B21-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/8.204744"},{"key":"B22-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/78.285650"},{"key":"B23-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2002.806865"},{"key":"B24-2014-418192","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2006.880257"},{"key":"B25-2014-418192","first-page":"43","volume-title":"Proceedings of the 8th Annual Workshop on Adaptive Sensor Array Processing","author":"Bell K.
