Software suites our own modulated system , which can be modified according to customers needs 3 .套裝軟體:自有的模組化系統(tǒng),并可依客戶需求修改。
Besides , we may overcome the shortcoming and the hinder of resource and market by developing science and technology and modulating system 我們可以通過科技的進(jìn)步與制度的調(diào)整來克服資源稟賦和市場環(huán)境的不足和制約。
This method not only modulates system capacity by using refrigerants of environmental protection , but also avoids additional energy consumption . it is likely to gain better modulation effect than other methods 這種調(diào)節(jié)方式不但利用了環(huán)保型的混合工質(zhì)有效地調(diào)節(jié)了制冷系統(tǒng)的制冷量,而且不產(chǎn)生附加能量損失,與其他容量調(diào)節(jié)方式相比,有可能獲得更好的調(diào)節(jié)效果。
This dissertation analyses the design idea and method for the direct spreading sequence msk modulate system with an error control function . it gives the matlab simulate result and the performance analysis through the modeling process 本文闡述和分析了一個(gè)帶有差錯(cuò)控制的直擴(kuò)序列msk調(diào)制系統(tǒng)的設(shè)計(jì)原理與方法,詳細(xì)分析和推導(dǎo)了系統(tǒng)的建模過程并給出基于matlab的仿真結(jié)果與性能分析。
The paper points out that only with feasible macro - management and modulating system in accordance of market economy , can government put the development of real estate into the right track so as to see its sound , sustainable and harmonious advance 因此,各級政府必須從房地產(chǎn)行業(yè)目前的機(jī)制與現(xiàn)存的問題出發(fā),建立與市場經(jīng)濟(jì)相適應(yīng)的房地產(chǎn)業(yè)宏觀調(diào)控的長效機(jī)制,真正使房地產(chǎn)業(yè)長期穩(wěn)定健康的發(fā)展。
With the established rf front - end system simulation platform , adding the digital modulated baseband signal , this paper simulated the multifold digital modulated signal ’ s transmission , such as 2ask , qpsk , and 16qam . then researches of power compression and phase noise of local oscillation influence the bit error ratio for different modulated system . the designing is satisfied multifold functions request with the high - powered and integrated broadband rf front - end 隨后在建立的寬帶射頻前端通用仿真平臺上,加入基帶數(shù)字調(diào)制信號,對多種數(shù)字調(diào)制格式的信號在該通用平臺上的傳輸作了研究,模擬了2ask 、 qpsk和16qam等調(diào)制格式信號的發(fā)射與接收,研究了功率壓縮和本振相位噪聲對不同調(diào)制的誤碼率影響,實(shí)現(xiàn)了滿足多種功能要求的寬帶高性能綜合射頻前端的設(shè)計(jì)。
