adjacent channel interference 中文意思是什麼

adjacent channel interference 解釋
鄰道干擾,相鄰通道干擾
  • 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...
  • interference : n. 1. 沖突，抵觸。2. 干涉，干預。3. 妨礙，打擾，阻礙物。4. 【物理學】干擾；干涉。
  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. Research on first adjacent channel interference in fm iboc dab

    系統第一鄰頻道干擾研究
  3. As the test signals of the trial will be transmitted via channels 35 and 37 ( never been used before to transmit television signals ), thus the television antenna systems using the said channels or the adjacent channels 34, 36 and 38 for other usages, such as the video cassette recorder ( vcr ) channel or closed circuit channel, might encounter interference during the said period

    是次測試使用的第35及37頻道，由於以往未有用作電視訊號發射，故任何電視天線系統如透過以上頻道或相鄰頻道（即34 、 36及38 ） ，作其他用途，例如用作錄影機播帶頻道，保安攝影機頻道等，將可能受到干擾。
  4. Adjacent - channel interference

    通道干擾
  5. For implement of wide band modulation, multi - carries and elimination of adjacent channel interference to satisfy ber requirement in wcdma system, which is most popular in 3g technology, the linearity requirement of the base station power amplifier becomes tighter

    以wcdma為代表的第三代移動通信技術，為實現寬帶調制、多載波應用，同時減小鄰通道干擾以滿足通信系統的誤碼率要求，對基站發射機功放的線性指標要求苛刻。
  6. From the research of ijf - oqpsk, we draw the conclusion that, compared with bpsk, qpsk and msk modems, in the band - limited and non - linear channel, it has nearly constant envelope, less spectral spreading, better pe performance and the less interference of the adjacent channel, et. so, it is more suitable for the satellite communication channel

    通過對ijf ? oqpsk的分析研究可知，它相對于傳統的bpsk和qpsk調制方式，在帶限非線性通道下，具有包絡近似恆定，頻譜擴展小， eb no惡化小，對鄰道產生干擾弱等優點，因而它更適合於衛星通道。
  7. Aci adjacent channel interference

    鄰頻干擾
  8. 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。
  9. Especially in recently about ten years, because cdma communication rapidly is developing and the amount of user is increasing in striking speed, the capability of communication give prominence to fall. because capacity of channel is limited by interference, especially for the interference from the same channels and the adjacent channels

    特別是近十幾年來，由於移動通信的迅猛發展，移動用戶的數量以驚人的速度在擴張，這樣由於用戶數量增長而造成通信質量的下降矛盾就顯得特別突出。由於通道的容量是由干擾所限定的，尤其是同通道干擾和鄰通道干擾的影響更為嚴重。
