Abstract

A new concept development and practical implementation of OFDM based secondary cognitive link are presented in this paper. Coexistence of secondary user employing Orthogonal Frequency Division Multiplexing (OFDM) and primary user employing Frequency Hopping (FH) is achieved. Secondary and primary links are realized using Universal Software Radio Peripheral (USRP) N210 platforms. Cognitive features of spectrum sensing and changing transmission parameters are implemented. Some experimental results are presented.
