摘要：
In this paper,a new transmission scheme for Fractional Fourier Domain Transform Communication System(FrFDCS) based on OFDM is proposed,which can be potentially applied in transmitting control information in the cognitive radio(CR) network.The proposed system can take advantage of concentration property of non-stationary signals in fractional domain to obtain a better performance against Chirp like jammers.Meanwhile,Chirp format subcarriers of fractional domain OFDM can solve the orthogonality degradation in the traditional OFDM system,when it comes to the time-frequency-selective channel.The signal model is designed for the OFDM-based FrFDCS and the BER performance in the AWGN channel is analyzed and simulated as well.
