Abstract(in English) Cognitive radio that can recognize surrounding wireless environments and select the best communication environment attracts attention because of limited frequency resources. Various methods of cognitive radio are considered, which are classified into two schemes. One is dynamic access that decides communication bands according communication situations with considering surrounding bandwidths. The other is environmental adaptive communication that recognizes diversifying wireless environments and selects the best communication method. This paper discusses a hardware design method of OFDM cognitive radio. The spectrum sensing and baseband processing circuits have been implemented into hardware to realize the cognitive radio systems having variable parameters of OFDM communication. The designed circuits have been evaluated in circuit area and power dissipation. The prototyping of spectrum sensing hardware has been constructed on a FPGA board.
