Study of throughput optimization for OFDM based D2D distributed communication system

Abstract

In recently with the popularity of wireless devices and multimedia systems for mobiles and tablets the demand for networks is increasing which has caused the data transmission of wireless communication systems to explode rapidly However the number of base stations has not been effectively grown which makes base stations more burdened Therefore Device to Device (D2D) communication transmission technology is more and more discussed Because of D2D communication devices directly transfer with others without using the base staion the overall transmission amount can be effectively increased and the burden on the base station can be reduced This paper will explore the optimization and analysis of Ad-hoc D2D data transmission rate based the distributed architecture In the SINR limit the limits of the upper and lower power and the lower limit of single data transmission rate Finally the main solution is Lagrange multiplier method and gradient descent
