Beschreibung
Zusammenfassung:	The invention consists of an ADC used to convert the received analog signal into the digital signal, a controller used to determine the modulation mode, a single carrier signal processor used to process single carrier demodulation signal, and a multi carrier demodulator used to process multi carrier demodulation signal. Wherein, the controller detects at least one reference signal from single carrier signal processor and the multi carrier signal processor, and in term of the reference signal, determines the demodulation mode of the digital signal. And when the modulation mode of the digital signal is indicated as a single carrier modulation mode, the controller sends the digital signal from ADC to the single carrier signal processor to process it. When the modulation mode of the digital signal is indicated as a multi carrier modulation mode, the controller sends the digital signal from ADC to the multi carrier signal processor to process it.
