【摘要】：為解決當(dāng)前5G無線移動異構(gòu)網(wǎng)絡(luò)數(shù)據(jù)吞吐算法中存在的虛擬分區(qū)間信號漂移嚴(yán)重,且難以實(shí)現(xiàn)用戶終端與小區(qū)基站之間平衡切換的不足,提出基于密集虛擬分區(qū)信道篩選機(jī)制的5G無線移動異構(gòu)網(wǎng)絡(luò)吞吐量優(yōu)化算法。通過5G信號密集化過程,構(gòu)建密集采樣機(jī)制,將離散的信號密集進(jìn)行并發(fā)多路處理;采取虛擬分區(qū)映射機(jī)制,將待傳輸?shù)?G信號精確劃入最佳匹配的分區(qū)中,降低高密度無線信號在發(fā)射接收過程中的互相影響;構(gòu)造信道傳輸矩陣映射機(jī)制,通過引入拉氏變換變化技術(shù),提高信號傳輸矩陣中可承載的數(shù)據(jù)上傳帶寬容量,聯(lián)合采取容量擴(kuò)容機(jī)制,改善信號密集條件下5G信號可利用的上傳帶寬容量。仿真結(jié)果表明,與當(dāng)前UPOS-1、UP5G-Plus、UPC-ad算法相比,在5G無線網(wǎng)絡(luò)異構(gòu)程度較高時,該算法擁有更高的數(shù)據(jù)吞吐量,在節(jié)點(diǎn)密集條件下能夠有效提升數(shù)據(jù)傳輸效率,顯著削弱了小區(qū)間同頻信號的互相干擾。
[Abstract]:In order to solve the problem that the virtual sub-interval signal drift is serious in the current 5G wireless mobile heterogeneous network data throughput algorithm, it is difficult to realize the balanced handover between the user terminal and the cell base station. A 5G wireless mobile heterogeneous network throughput optimization algorithm based on dense virtual partition channel filtering mechanism is proposed. Through the process of 5G signal densification, the dense sampling mechanism is constructed, the discrete signal is processed simultaneously and multiplex, and the 5G signal to be transmitted is accurately divided into the best matching partition by using the virtual partition mapping mechanism. The mutual influence of high density wireless signal during transmission and reception is reduced, and the channel transmission matrix mapping mechanism is constructed. By introducing the Laplace transform change technique, the data upload bandwidth capacity of the signal transmission matrix can be increased. The capacity expansion mechanism is adopted to improve the available upload bandwidth of 5G signal under the condition of dense signal. The simulation results show that compared with the current UPOS-1 UP5G-PlusPad algorithm, the algorithm has higher data throughput when the heterogeneity of the 5G wireless network is high, and can effectively improve the data transmission efficiency under the condition of dense nodes. The mutual interference of the same frequency signal in the interval is significantly reduced.
