adjacent-channel power 中文意思是什麼
adjacent-channel power
解釋
鄰道功率-
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。 -
In this dissertation, researching from the basic concept of large signal network analysis, we discuss the measurement theory and technology of rf network nonlinearity and the characterization technology of intermodulation distortion in detail, and analyse some nonlinear characteristic excited with a one tone or multi - tone, such as am - am, harmonic distortion, intermodulation distortion, adjacent channel power ratio and how to qualitatively analyse nonlinearity of rf network to make the measurement and calibration
本課題從大信號網路分析的基本概念出發，詳細討論了射頻網路非線性的測量理論和技術以及互調失真表徵技術，分析了在單頻音和多頻音信號激勵下的一些非線性特性，如am - am ， am - pm ，諧波失真，互調失真（ imd ）和臨近通道功率比（ acpr ）等，以及根據包絡域方法定性地分析射頻微波網路的非線性特性，以此來進行射頻網路的非線性測量和校準。 -
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。 -
Analysis of a forward link cdma signal spectral regrowth and adjacent - channel power ratio
信號前向鏈路頻譜增生和鄰道功率比估計 -
In communication systems like this, on account of nonlinearity which may arouse intermodulation of power amplifier may bringing the increaseing of ber because interferes from adjacent channel. hence, we did the analysis of relationship between im3 and ber in the system
但是在正是因為採取這種調制方式，由於功率放大器的（ pa ）非線性失真會引起交調效應產生同頻及鄰頻通道的干擾而使誤比特率（ ber ）增加。 -
