Abstract :
As the communication system for a new indoor short distance radio-communication for wireless personal area networks (WPAN), the ultra wideband (UWB) system is examined towards standardization. In such an examination, the UWB system uses limited bandwidth and transmitted power in order to avoid interference with other systems. The possibility of realization, with such as the multiband type, which uses a subcarrier, is higher than the system which does not use a subcarrier, like the impulse radio (IR) system considered conventionally. The "modified Hermite pulse", as proposed for application to the IR system, is modulated, and the application to UWB of the "modulated and modified Hermite pulse", improved so that only a desired bandwidth might be occupied, is proposed. Furthermore, with respect to the characteristics and the performance of the waveform, it is evaluated using computer simulations, and is shown to excel in the BER characteristic as compared with a multiband-FHTH system.
