APPARATUS AND METHOD FOR DETECTING SIGNAL USING BLOCK DATA DECOMPOSITION

摘要

PURPOSE: A signal detecting device and method thereof using a block data analysis decomposition are provided to conveniently detect an active signal in a poor communication environment which has poor SNR and SINR. CONSTITUTION: An extracting unit(130) extracts a main eigen vector having relatively large eigen value among eigen vectors of matrix. The matrix obtains a matrix decomposition algorithm by applying the algorithm. A correlation value calculation unit(150) calculates correlation between a pre-stored main eigen vector including the characteristic information of a carrier signal and standards matrices.
