Hace 4 días · Last Updated : 23 May, 2024. Spread spectrum is a method of transmitting radio signals over a wide range of frequencies. It spreads the signal over a broader bandwidth than the minimum required to send the information, which provides advantages such as increased resistance to interference, improved security, and enhanced privacy.
Spread spectrum. Lo spread-spectrum (in italiano spettro espanso) indica una tecnica di trasmissione in cui il segnale informativo viene trasmesso su una banda di frequenze che è considerevolmente più ampia di quella effettivamente necessaria alla trasmissione dell' informazione contenuta nel segnale originario stesso (v. trasmissioni in ...
A spread spectrum communications system is one that is built upon the principle of transmitting information signals over a much wider bandwidth than is strictly necessary for transferring the information. By transmitting over a larger bandwidth, robustness against external narrowband interference is increased, since the wider the bandwidth of any transmitted signal the lower will be the ...
5 de jun. de 2012 · Spread spectrum is a technique that increases signal bandwidth beyond the minimum necessary for data communication. There are many reasons for doing this. Spread-spectrum techniques can hide a signal below the noise floor, making it difficult to detect. Spread spectrum also mitigates the performance degradation due to intersymbol and narrowband ...
周波数ホッピング・スペクトラム拡散 （ 英語: frequency hopping spread spectrum 、 FHSS ）とも言う。. 送信側と受信側でホッピング・シーケンスやホッピング・パターンと呼ぶ一定の規則を規定し、それに従って一定の通信帯域の中で高速に通信周波数を切り替えて ...
8 de sept. de 2014 · Spread-spectrum (SS) technology uses a sequential noise-like signal to spread the normally narrowband information signal over a relatively wide band of radio frequencies. The receiver correlates the received signals to retrieve the original information signal. Using wideband, noise-like signals to “spread the spectrum” used makes the ...
Spread spectrum is a technique used for wireless communications in telecommunication and radio communication. In this technique, the frequency of the transmitted signal, i.e., an electrical signal, electromagnetic signal, or acoustic signal, is deliberately varied and generates a much greater bandwidth than the signal would have if its ...
