RECEIVING DEVICE OF A MULTI-BAND ULTRA WIDEBAND COMMUNICATION SYSTEM AND A RECEIVING METHOD THEREOF, ESPECIALLY CONCERNED IN COMPENSATING FOR DIFFERENT PATH ATTENUATIONS ACCORDING TO EACH SUB BAND

摘要

PURPOSE: A receiving device of a multi-band UWB(Ultra Wideband) communication system and a receiving method thereof are provided to differently control integration times according to each sub band, in order to compensate for different path attenuations in accordance with each sub band, thereby lowering an average bit error rate while realizing a high-speed data rate. CONSTITUTION: A multi-band index generator(100) generates a multi-band index corresponding to a sub band where a receiving signal is transmitted. A multi-band frequency generator(120) generates a multi-band frequency for the sub band by corresponding to the multi-band index. A multiplier(130) outputs a signal produced by multiplying the receiving signal by the multi-band frequency. A correlation receiver(140) integrates the signal outputted from the multiplier(130) according to a set integration time, and outputs the integrated signal. A buffer(160) buffers the outputted signal such that the buffered signal can be outputted in predetermined data rate.
