Considering the two limitations of UWB baseband modulation, the UWB carrier envelope modulation (CEM) scheme is presented in the paper. The UWB binary orthogonal carrier envelope modulation (BOCEM) is discussed as an example to show the realization of UWB carrier-based modulation system. The carrier frequency selection criteria is also derived. The performance analysis and simulation results show the feasibility of the modulation scheme. The UWB carrier envelope modulation (CEM) scheme is different from the present ultra-short pulse UWB and multiband UWB and provides a new design idea for UWB. With the concept of carrier being applied in UWB modulation, the UWB signal processing is extended from the time domain to the frequency domain and a new sight is provided for further development of UWB wireless communication.
