adjacent channel frequency 中文意思是什麼

adjacent channel frequency 解釋
鄰頻道頻率
  • adjacent : adj. 1. 毗鄰的，鄰近的。2. （時間上）緊接著的。
  • channel : n 1 水路，水道，渠，溝；海峽；河床，河底。2 （柱等的）槽，凹縫；【機械工程】槽鐵，凹形鐵。3 〈比...
  • frequency : n. 1. 屢次，頻仍，頻繁。2. （脈搏等的）次數，出現率；頻度；【物理學】頻率，周率。
  1. Since the envelope of modulated signal fluctuates, these methods generate unwanted intermodulation distortion ( imd ) products in a nonlinear radio frequency ( rf ) power amplifier ( pa ). so it is necessary to use linearization technique to reduce the adjacent channel interference ( aci )

    但包絡變化的調制信號經過非線性射頻功放后會產生交調分量，因此必須採用線性化技術來減少由此產生的鄰道干擾。
  2. So, at the frequency 1920mhz, phs will be adjacent to wcdma uplink, there will be fairly strong adjacent channel interference between them, compared to phs and wcdma downlink, which could be neglected

    Phs系統將緊鄰wcdma系統的上行頻帶，在1920mhz頻點附近兩系統將會對彼此產生比較強的鄰頻干擾，由於頻帶距離較遠，可以忽略wcdma下行頻帶和phs之間的干擾。
  3. Therefore, the information obtained from the adjacent seismic channel can he extrapolated to the other channel by using time - frequency analysis method of wavelet

    據此，利用小波時頻分析技術方法，可以把相鄰道的信息外推到其它地震道上。
  4. In addition, the high and low frequency information of the adjacent channel can be transformed to the other seismic channel by taking the advantage of better similarity of subsection time - frequency analysis of seismic data, as well as the capability of learning, training and memorizing of the wavelet network

    同時，利用地震資料分段時頻分析的相似性較好和小波網路學習、訓練及記憶能力較強的特點，可以較好地把井旁道的高、低頻信息轉換到相鄰道上。
