Abstract

Abstract4G Long Term Evolution (LTE) has a standard for wireless communication with high-speed data access on cellular phones which have standard parameter i.e. power control. Power control is a method to avoid interference inter-users, as a result of power variations. Interference inter-users will cause performance limitations of the quality of service telecommunications operator. In this paper, we will design power control on the uplink channel based on the Signal to Interference Ratio (SIR) so that power level of mobile station (MS) are approximately equal. Simulation results show that power of MS can reach -7 dB, average time above 17 ms. The results of the SIR can order MS to equalize the SIR power levels transmitted by some MS with SIR reference value.

研究kinerja kendali daya kanal上行4g lte berdasarkan信噪比(sir)

摘要4g LTE (Long Term Evolution)是一种具有标准参数(即功率控制)的移动电话高速数据接入无线通信标准。功率控制是一种避免用户间由于功率变化而产生干扰的方法。用户间的干扰会对电信运营商的业务质量造成性能限制。在本文中，我们将基于信干扰比(SIR)设计上行信道的功率控制，使移动站(MS)的功率水平近似相等。仿真结果表明，MS的功率可达-7 dB，平均时间在17 MS以上。SIR的结果可以命令MS将某些MS传输的SIR功率电平与SIR参考值相等。摘要:4g长期演进(LTE)记忆基标准komunikasi nirkabel akses数据berkeepatan tinggi pad手机销售商yang记忆基参数标准yitu kendali daya。Kendali daya merupakan metuk menghindari interferensi antar pengguna akibat varasi daya。干扰信号antar pengguna menyebabkan keterbatasan kinerja kualitas layan运营商telekomunikasi。Pada penelitian ini, akan dirancang kendali daya kanal上行链路berdasarkan SIR agar daya移动站(MS) mendekati sama。Hasil simulasi menunjukkan bahwa daya MS datapapi -7 dB, reratwaktudi数据17 MS。Hasil menunjukkan, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIR, SIRKata Kunci: kendali daya, kanal上行，SIR，移动基站
