  • Abstract
    Some experimental results of development of the concept and practical implementation of OFDM based secondary cognitive link are presented in this paper. Secondary link is realized using USRP N210 platforms. Several algorithms to overcome transmission problems are used, such as frequency offset compensation, time synchronization and channel estimation. Also cognitive feature of changing transmission parameters is implemented.
