High-frequency radio signal receiving apparatus for digital communication |
摘要 |
<p>A high-frequency radio signal receiving apparatus for digital communication includes a receiving antenna (1) for receiving a high-frequency radio wave, a frequency converter (3) for converting a signal supplied from the receiving antenna (1) through a wide-band bandpass filter (2) into a signal of an intermediate frequency band, an impulsive noise detecting unit (6) for detecting impulsive noise on the basis of a signal outputted from the frequency converter (3). The apparatus further includes an impulsive noise correcting unit (7) for correcting the signal outputted from the frequency converter (3) in dependence on a signal outputted from the impulsive noise detecting means (6), and a demodulating means (5) for demodulating a signal outputted from the impulsive noise correcting means (7) and supplied by way of a narrowband bandpass filter (4). <IMAGE></p> |
