So , memory effects of nonlinear pa model are considered in system - level simulation 系統(tǒng)級(jí)仿真中非線性功放模型必須考慮記憶效應(yīng)。
3 . the author has found a suitable tool used for system - level simulation ? elanix systemview , and developed some key modules to construct a systemview simulation for the fdma ? wtdm conversion system , which would be very helpful for its hardware implementation 選擇系統(tǒng)級(jí)仿真工具elanixsystemview ,為構(gòu)建fdma - cwtdm轉(zhuǎn)換的systemview仿真模型建立了關(guān)鍵模塊,為星上fdma - cwtdm轉(zhuǎn)換的硬件實(shí)現(xiàn)打下了良好的基礎(chǔ)。
Much reference of the algorithms and models can be got from the performance results for the practical design and layout . system - level simulation of hsupa builds the integrated platform and key models to describe and simulate the common structure and features of the radio network , including cell layout , path gain , traffic model , power control , handover , etc . , also the special ones of hsupa , including mac - es / e , node b controlled scheduling , harq , shorter tti , etc . 所謂hsupa系統(tǒng)級(jí)仿真就是要搭建系統(tǒng)級(jí)的仿真平臺(tái),對(duì)無線網(wǎng)絡(luò)的公共結(jié)構(gòu)和特性(例如小區(qū)布局,傳播模型,衰落信道,天線模型,功率控制,切換, ue的分布和移動(dòng),業(yè)務(wù)的建立終止和中斷等)和hsupa的專有結(jié)構(gòu)和特性( mac - es / e , nodeb控制的調(diào)度, harq ,更短的tti )進(jìn)行描述和建模。
