In cognitive radio, the design of an effective control channel must be based on a transmission scheme that satisfies two challenging requirements: long transmission range and low emission power. This paper proposes a novel transmission scheme that effectively satisfies these two requirements by combining an orthogonal frequency division multiplexing (OFDM) scheme with transform domain communication system (TDCS) technology. We formulate, for the first time, a mathematical model of a transform domain communication system (TDCS). Based on this model, we then design a new transmission scheme, named the OFDM-based TDCS for control message transmissions. Our analytical and numerical analyses show that OFDM-based TDCS successfully satisfies both the transmission range and the emission power requirements of a control message transmission scheme for cognitive radio networks. Further, we propose one implementation option, named interleaved OFDM-based TDCS, for the OFDM-based TDCS scheme. This optional scheme has low implementation complexity and is suitable for situations where spectrum is continuously available.
