A Comparative Study of Mimo Capacity with Different Antenna Topologies

Multiple input/multiple output (MIMO) is a hot topic in wireless communication and has great advantage in capacity. We investigate the influence of antenna topology on MIMO capacity and by comparing three topology schemes we find that selecting a proper antenna topology increases the capacity evidently. Three schemes under study are the traditional point-to-point concentrated antenna topology (...

Channel Measurement Based Antenna Synthesis for Mobile Automotive MIMO Communication Systems

In this paper a multiple input multiple output (MIMO) radio channel measurement system is presented that utilizes several software defined radio (SDR) platforms at the transmitter and at the receiver. The system hardware buildup and its calibration technique are presented. The channel measurement results are afterwards exploited for a special antenna synthesis method that was already proofed by...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...

A Compact 4G MIMO Antenna Integrated with a 5G Array for Current and Future Mobile Handsets

A novel integrated antenna solution for wireless handheld devices is proposed for the existing 4G standards and upcoming 5G systems for broadband, high data rate communications. The complete antenna system is a unique combination of a multiple-input-multiple-output (MIMO) antenna system at microwave frequencies and a millimeter(mm)-wave antenna array. The MIMO antenna system consists of two rea...
