【摘要】：科技不斷發(fā)展,人們對于通信有了更高的要求。之前包括現(xiàn)在有很多學(xué)者和機(jī)構(gòu)致力于研究如何進(jìn)一步提升通信系統(tǒng)的容量。而且未來的通信網(wǎng)將會(huì)有500億的設(shè)備互聯(lián),通信容量將會(huì)是目前網(wǎng)絡(luò)所能提供的1000倍,如果單純地依靠耗用更多的能量來支持如此龐大的通信量,無疑將會(huì)付出不可想象的成本代價(jià)以及環(huán)境污染。因此,無論是學(xué)術(shù)界還是產(chǎn)業(yè)界,都在研究如何在與目前網(wǎng)絡(luò)消耗能量相差無幾的情況下,將系統(tǒng)的容量提高到近1000倍,也就是說研究如何將系統(tǒng)中的能量效率提高到傳統(tǒng)系統(tǒng)的1000倍[2]。因此,能量效率成為了下一代無線通信的關(guān)鍵詞。在多小區(qū)通信系統(tǒng)中,Co MP與MIMO技術(shù)的結(jié)合可以很好地解決小區(qū)邊緣用戶通信干擾大、吞吐量低的問題,因此本文對這兩種技術(shù)展開相關(guān)研究和對比分析,選擇合適的模式來為整個(gè)系統(tǒng)的資源管理提供更好的服務(wù),以支持不同用戶的業(yè)務(wù)需求,達(dá)到優(yōu)化系統(tǒng)中能量效率和頻譜效率的目的。首先,本文對蜂窩小區(qū)中下行通信鏈路的相關(guān)流程進(jìn)行介紹,在此基礎(chǔ)上,研究了相關(guān)的關(guān)鍵技術(shù),分析了3種Co MP模式以及4種線性波束賦形方案,最后選定CS/CB以及SLNR作為本文的方案。介紹了傳統(tǒng)的資源管理方案以及Qo S的相關(guān)定義。然后,對系統(tǒng)中的能量效率展開研究,基于3小區(qū)的通信場景,建立了滿足用戶數(shù)據(jù)速率需求的資源分配和功率分配數(shù)學(xué)模型,然后設(shè)計(jì)迭代算法進(jìn)行求解,并進(jìn)行仿真和對比分析。最后,分析系統(tǒng)中能量效率和頻譜效率的關(guān)系,以加權(quán)的能量效率和頻譜效率和為目標(biāo)函數(shù)進(jìn)行資源分配和功率分配,并考慮不同用戶的速率需求以及時(shí)延限制,進(jìn)一步分析系統(tǒng)參數(shù)對于這兩個(gè)指標(biāo)的影響,說明不同系統(tǒng)需求下如何選擇合適的參數(shù)以更好地滿足不同用戶的需求,同時(shí)也對系統(tǒng)中用戶的GBR滿意度以及丟包率性能進(jìn)行了分析。
[Abstract]:Technology continues to develop, and people have a higher demand for communications. There are many scholars and institutions that are now working to study how to further enhance the capacity of the communication system. And the future communication network will have 50 billion devices interconnected, and the communication capacity will be 1000 times the current network can provide, if only rely on consumption. More energy to support such a huge amount of communication will undoubtedly pay unimaginable cost and environmental pollution. Therefore, both academia and industry are studying how to increase the capacity of the system to nearly 1000 times that of current network consumption, that is, how to study the system The energy efficiency in the traditional system is 1000 times [2]., so the energy efficiency has become the key word for the next generation of wireless communication. In the multi cell communication system, the combination of Co MP and MIMO technology can solve the problem of large communication interference and low throughput of the cell edge users. Therefore, this paper carries out the related research on these two technologies and Comparative analysis, select the appropriate mode to provide better service for the whole system resource management, to support the business needs of different users, to optimize the energy efficiency and spectrum efficiency in the system. First, this paper introduces the related flow of the downlink communication link in the cellular cell, and on this basis, the relevant customs are studied. Key technology, 3 Co MP modes and 4 linear beam forming schemes are analyzed. Finally, CS/CB and SLNR are selected as the scheme. The traditional resource management scheme and the related definition of Qo S are introduced. Then, the energy efficiency of the system is studied. Based on the communication scene of the 3 cell, the user data rate requirement is set up. The mathematical model of resource allocation and power allocation is designed, then the iterative algorithm is designed to be solved, and the simulation and contrast analysis are carried out. Finally, the relationship between the energy efficiency and the spectrum efficiency is analyzed. The energy efficiency and spectral efficiency are weighted and the resource allocation and power allocation are used for the target function, and the rate requirements of different users are taken into consideration. The effect of system parameters on these two indexes is analyzed in time, and how to choose appropriate parameters to better meet the needs of different users is explained under different system requirements. At the same time, the GBR satisfaction and packet loss rate performance of the users are also analyzed.
