@ARTICLE{Aliasgari, author = {Aliasgari, Mohammad and Fakhraie, Sied Mehdi and }, title = { Deep Out-of-Band Radiation Reduction By Using Joint Filterbank and Cancellation Carriers in Cognitive Radios }, volume = {5}, number = {2}, abstract ={A deep spectrum sculpting is necessary to enable coexistence between a cognitive radio (CR) user and a licensed user which has low dynamic range and is susceptible to interferences. In this paper, we propose to use joint filter-bank based multicarrier system and cancellation carriers to guarantee an almost free out-of-band interference transmission and keep the quality of services of licensed adjacent bands unchanged. We investigate the performance of the proposed method with different well-known existing methods from viewpoints of the average level of out-ofband power, spectral efficiency, and computational complexity. }, URL = {http://ijict.itrc.ac.ir/article-1-156-en.html}, eprint = {http://ijict.itrc.ac.ir/article-1-156-en.pdf}, journal = {International Journal of Information and Communication Technology Research}, doi = {}, year = {2013} }
