UNIVERSAL BLIND MODE DETECTOR, FFT-MODE DETECTOR, GUARD-MODE DETECTOR AND MEMORY SHARING STRUCTURE OF THE SAME UNIVERSAL BLIND MODE DETECTOR AND METHOD OF DETECTING UNIVERSAL BLIND MODE

摘要

PURPOSE: A universal blind mode detector, FFT-mode detector, a guard-mode detector and a memory sharing structure of the same universal blind mode detector and a method of detecting universal blind mode are provided to increase the integration of a chip by using a minimum memory usage through a memory sharing method. CONSTITUTION: An integration mode detector includes an RF tuner, an AGC part, a communication service mode detection part, and a channel decoding part. The RF tuner(2000) converts a received signal to a baseband frequency(IF) signal. The AGC part(3000) confirms whether communication service is available or not by being connected with the RF tuner and checking RSSI(Received Signal Strength Indication). The communication service mode detection part(1000) detects the corresponding communication service mode signal by confirming which communication service mode signal is.
