  1. In - band - adjacent - channel ibac

    帶內鄰頻
  2. 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。
  3. 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。
  4. Present phs standard prescribed a rather loose out - band and emission power requirements, which will cause severe interference to adjacent frequency band. the wcdma standard requires a more strict rf performance at the account of already existed systems

    Phs系統對帶外和雜散指標定得比較寬松，而wcdma的協議標準里專門考慮了對現有系統的干擾情況，因而對射頻指標要求得比較嚴格。
