A DIGITAL MULTIMEDIA SIGNAL RECEIVER FOR PROCESSING A SINGLE CARRIER MODULATED SIGNAL AND A MULTI CARRIER MODULATED SIGNAL AND A RECEIVING METHOD THEREOF

摘要

PURPOSE: A digital multimedia signal receiver and a receiving method thereof are provided to process a single carrier modulated signal and a multi carrier modulated signal to realize superior performance. CONSTITUTION: A received analog signal is converted into a digital signal(S420). The digital signal is demodulated according to a modulation mode command(S430). The modulation mode command shows whether the digital signal is a single carrier modulated signal and a multi carrier modulated signal. The demodulated signal is deinterleaved. The deinterleaved signal is LDPC(Low-Density Parity-Check)-decoded.
