Abstract: PURPOSE: An apparatus and a method for estimating the signal arrival direction in a communication system are provided to estimate the arrival direction of a signal using a signal obtained through filtering of a noise region. CONSTITUTION: A signal arrival direction estimating apparatus(100) comprises a signal receiver(110), a preprocessor(120), a signal rearrangement processor(130), and a signal arrival direction estimator(140). The preprocessor converts a signal received through the signal receiver into a frequency region and denoises the converted time sample. The signal rearrangement processor measures an occupied bandwidth through spectrum analysis of the denoised signal and filters a noise region from the denoised signal based on the occupied bandwidth. The signal arrival direction estimator estimates a signal arrival direction using the filtered signal.

Abstract: PURPOSE: A system and method for selecting a white Gaussian noise band using singular value decomposition are provided to objectively and effectively select a frequency or a frequency band which is configured by only wireless background noise. CONSTITUTION: A frequency selecting unit(110) selects a first frequency band. A signal checking unit(120) checks whether a signal is included in the first frequency band. If a signal is not included in the first frequency band, a target frequency determining unit(130) determines the first frequency band as a measurement target frequency band. A noise measuring unit(140) measures a wireless background noise in the determined measurement target frequency band.
