Abstract: A receiving device and a receiving method of an ultra wideband wireless communication system are provided to obtain a signal precisely and match the synchronization by using a low system clock with a parallel structure. A serial to parallel converter(201) samples a serial data signal to n parallel data signals and outputs the sampled signal after converting an analog signal to a pulse signal of a digital signal. A matched filter bank part(202) matches and filters the n parallel data. A correlation bank part(203) correlates the output of the matched filter bank part with the ternary code and outputs the correlated value. A preamble boundary detector(204) receives the signal outputted from the correlation bank part and detects the start boundary of the ternary code. A multipath profile calculator(208) receives the signal outputted from the correlation bank part and calculates the multipath phase and amplitude change. A data demodulator detects and demodulates the multipath phase and amplitude change by using the outputted parallel data signal.
