PURPOSE: A testing and verifying system for UWB(Ultra Wideband) communication system design is provided to supply an alternative plan for a variable hardware design method by setting parameters according to a user's intention and varying supplied signals, thereby enabling a concrete configuration for UWB communication. CONSTITUTION: A host comprises as follows. A period and PN setup unit(140) sets the width of a pulse, a repeated period, a setup of a PN code, and a pulse generation method for an impulse shape. A data pattern setup unit(110) inputs/sets patterns of data. A sound and video data selector(120) sets and transmits sound data and video data through the host. A sound and video input device selector(130) is used for selecting a sound and video device from an outer device. A controller(150) receives the sound data and the video data, and determines standards of the data in accordance with a serial communication unit of a serial communication unit interface(180). A coder(160) safely transmits the data while restoring data of a receiving system.
