Abstract
A wireless signal receiving device is disclosed that includes an RF tuner for receiving a wireless signal over an antenna radiator, a demodulator for demodulating the received signal to output a signal of a first frequency band, and a spread spectrum modulator for spreading a frequency spectrum of the demodulated signal to output a signal of a second frequency band. In addition, various embodiments recognized through the specification are possible.
Claims10
A wireless signal receiving device, comprising:
- a radio frequency (RF) tuner configured to receive a wireless signal through an antenna radiator;
- a demodulator configured to demodulate the wireless signal to output a transport stream (TS) signal of a first frequency band;
- and
- a spread spectrum modulator comprising:
- a frequency controller configured to determine a mixing signal frequency based on frequency information of the TS signal;
- a signal generator configured to output a mixing signal having the determined mixing signal frequency;
- and
- a mixer configured to mix the TS signal of the first frequency band with the mixing signal of the mixing signal frequency, to spread a frequency spectrum of the TS signal and output a demodulated signal of a second frequency band in which an intensity level of an electromagnetic wave is lower than an intensity level of an electromagnetic wave of the TS signal.
