鄰線干擾 的英文怎麼說
中文拼音 [līnxiàngānrǎo]
鄰線干擾
英文
interference from neighboring line-
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。The predistortion, which aims at compensating for the nonlinear distortion caused by the power amplifier, has a good performance in eliminating the nonlinear distortion of am / am & am / pm, improving the aci and spectrum efficiency
預失真技術是針對射頻功率放大器非線性而提出的一種補償技術，可以有效消除由非線性造成的傳輸信號的幅度和相位失真，降低信號鄰道干擾（ aci ） ，提高頻譜利用效率。5 fixed protection / anchors should not interfere with nearby existing routes
5固定支點錨栓之安裝不應干擾到其他鄰近的路線。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。The directional routing protocol ds _ dsr put forward by the author is the improvement of the current protocol dsr, complete routine discovery and maintenance by directional neighbor nodes routing table, source routing and directional steering. the research discovers the application of the directional antenna, compare the omnidirectional antenna can increases the networks " total throughput, obviously reduces the co _ channel interference ( cci ), multiple access interference ( mai ), enlarges the nodes " signal and interference to noise ratio ( sinr ), and because of the high gain of directional antenna can realize the communication with farther distance and less jump, end to end delay can decrease deeply, simultaneously, security of networks can be improved partially, the node energy also can be saved easily by power control
本文提出的定向路由協議ds _ dsr是基於對現有協議dsr的改進下實現的，通過定向鄰節點路由表、定向源路由和定向搜索來完成路由發現與維護。研究發現，定向天線的應用，相比全向天線可明顯提高網路的總的吞吐量，減少通道干擾、多址干擾，提高信干噪比，且由於定向天線的高增益可實現較遠距離、較少跳數的通信，減少了路由發現時間，這樣大大減小了傳輸時延，網路的整體性能得到了不同程度的提高，同時部分地解決安全問題，通過功率控制還可較容易的實現節能的目的。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。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。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。Because an antenna beam has certain width, and the antenna on the earth will point to the adjacent satellites at its side lobe, the transmitting antenna may create interfering radiation ( which is known as uplink adjacent interference ), and the receiving antenna will also be interfered ( which is known as downlink adjacent interference )
由於天線波束具有一定的寬度，地面發送天線會在指向鄰星的方向上產生干擾輻射（上行鄰星干擾） ，地面接收天線也會在鄰星方向上接收到干擾信號（下行鄰星干擾） 。In order to limit such mutual interference, the operators of the adjacent satellites will follow the radio regulations by itu, to take appropriate measures and limit the power density of the carriers, as well as the antenna size
為了限制相互之間的干擾，兩顆鄰星的操作者會按照國際電聯制訂的《無線電規則》 ，對載波功率譜密度和地面天線口徑作適當的限制。Vehicles, boats and internal combustion engine driven devices - radio disturbance characteristics - limits and methods of measurement for the protection of receivers except those installed in the vehicle boat device itself or in adjacent vehicles boats devices
