发明名称 SIGNAL RECEIVER WITH DIGITAL FRONT END SUPPORTING MULTIPLE BAND AND SIGNAL RECEIVING METHOD USING THE SAME
摘要 <p>PURPOSE: A signal reception apparatus including a digital front end and signal reception method using the same are provided to variably control decimation rates according to the channel band or frequency bandwidth of a signal at the digital front end by inputting a channel selecting filter. CONSTITUTION: A CIC(Cascated Integrator Comb) decimation filter(110) reduces sampling rates of a reception signal. A CIC compensation filter(120) compensates errors generated in the CIC decimation filter. A re-sampler(130) controls the sampling rates of the reception signal. A channel selecting filter(140) rapidly filters a channel frequency band. The channel selecting filter eliminates noise except for signal bands.</p>
