A linear signal combination model for UWB applications

Systems that use UWB technology based on communication with baseband signals of very short duration recently attract attention in communication and radar application, and thereof have been improving rapidly. Because UWB signals occupy a spectrum that is spread about very wide frequency band, one of the principal issues that need to be considered in UWB applications is the frequency allocation. In order to minimize or prevent possible distorting interferences with existing communication systems, spectral distribution of mandatory EIRP limit values has been determined by FCC in UWB applications. In this study, a linear signal combination model has been established and on mathematical expressions have been provided for production of wave forms are suitable UWB emission mask specified by FCC.
