Spread-spectrum communication device |
摘要 |
A spread-spectrum communication device which substantially eliminates a narrow-band interfering signal contained in a spread signal over a wide range of frequency and which presents a good S/N ratio in a despread signal. A magnetostatic filter is used to limit the narrow-band interfering signal along with part of the spread signal. The limited spread signal and narrow-band interfering signal are despread by a matched filter. A plurality of correlation peaks, which are derived from the same symbol in the spread signal and are contained in the despread signal, are synthesized in a rake synthesizer or a post-detection integrator receiver.
