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
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
The present invention can be integrated with the detection of a variety of communication services to the OFDM scheme, and also other than the OFDM scheme, and the communication service to be integrated with the detection in integrated mode detection device, FFT- mode detection device of the detection device, the guard-mode detection device and provides a shared memory structure, and integration mode detection method. RF tuner for converting the integrated mode, the detection device is a received signal to a baseband frequency signal; Is connected to the RF tuner to determine the RSSI (Received Signal Strength Indication), AGC to determine whether or not a communication service (Automatic Gain Control) unit; If the AGC is present in the communication service identified in the service mode communication unit which detects the communication service mode signal to determine whether a communication service mode in which method signal detection section; And a channel decoding unit for performing decoding with respect to the detected signal; and a
