APPARATUS FOR ACQUIRED PREAMBLE SEQUENCE

摘要

PURPOSE: A preamble sequence detecting apparatus is provided to reduce hardware resources which are necessary to detect a preamble sequence by using a fourier transform method. CONSTITUTION: A standard signal creation unit(400) creates plural standard signals which include a specific length. An expansion unit(402) expands the created standard signal of the standard signal creation unit to a set ratio. Expansion ratios are variously established. A quantization unit(404) quantizes the standard signal in order to include a specific length according to the value of the standard signal.
