Provided are a multi-channel tuning receiver, including: a broadband radio frequency (RF) tuner to receive a broadband signal, divide the broadband signal into a plurality of signals, tune the divided signals, combine the tuned signals into a single signal, and output the combined single signal; an analog-to-digital (A/D) converter to convert the combined single signal to digital signal; a channelizer to extract only a bonded channel from the digital signal; and a plurality of demodulators to demodulate the bonded channel, and a multi-channel tuning method thereof.

Multi-channel tuning receiver and multi-channel tuning method thereof

Provided is a channel bonding receiving apparatus and method for expanding a channel bonding receiving band in a cable modem. The channel bonding receiving apparatus includes a channel bonding dividing unit for dividing a channel bonding broadband signal into a plurality of band signals and extracting a corresponding channel bonding signal from each of the divided band signals; and a channel routing unit for routing each of the extracted channel bonding signals to a corresponding demodulator.
