In the method, a preamble signal received from at least one neighbor BS is converted to a frequency response of a preamble sequence and Inverse Fast Fourier Transform (IFFT)-processing the preamble signal, an estimation period of the IFFT-processed preamble signal, corresponding to a Fast Fourier Transform (FFT) size, is divided into a predetermined number of blocks, carrier power values of the blocks are accumulated for a predetermined number of frames, an average of timing offsets of the frames corresponding to a position of a block having a maximum average of accumulated carrier values is determined to be a timing offset of the preamble signal, a carrier power value of the preamble signal is calculated using the timing offset, and a CNR of the preamble signal is estimated using the carrier power value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for estimating carrier-to-noise ratio and base station apparatus using the same in a wireless access system","description":"A method and an apparatus for estimating a Carrier-to-Noise Ratio (CNR) at a Base Station (BS) in a wireless access system are provided.
