Digital multimedia signal receiver and its receiving method

Abstract

The invention consists of a tuner used to down-convert multimedia signal, ADC used to convert the down-converted signal from tuner into the digital signal, a filter coefficient unit used to provide a filer coefficient set, a receiving filer used to filer the digital signal from ADC in term of the filer coefficient set, a demodulator used to demodulate the digital signal from the receiving filter in term of the instruction of modulation mode, and a channel decoder used to decode the demodulated signal from the demodulator.

Description

technical field [0001] The invention relates to a digital multimedia receiver and a digital multimedia signal receiving method, in particular to a receiving method for processing single-carrier modulated signals and multi-carrier modulated signals. Background technique [0002] In the era of multimedia communication and broadcasting, all countries in the world are digitizing analog broadcasting, especially in developed countries such as the United States, Europe and Japan, where digital broadcasting systems have been developed and put into use. With its rapid development, different standards for digital broadcasting have been proposed in different countries. [0003] On December 24, 1996, the US Federal Communications Commission (FCC) proposed the Advanced Television Systems Committee (ATSC) digital television standard as the next-generation television broadcasting standard. All terrestrial broadcast operators must comply with ATSC standards for t...
