A Cognitive Radio based Solution to Coexistence of FH and OFDM Signals Implemented on USRP N210 Platform

Blog Article

A new concept development and practical implementation of an OFDM based secondary cognitive link are presented in this paper.Coexistence of a secondary user employing Orthogonal Loaf Pan Frequency Division Multiplexing (OFDM) and a primary user Folic Acid/ Vitamin B-9 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.
