EE-SE Trade-Off of the 2BS-DMIMO System

Preetha. K | Rajkumari. M

Abstract: For high speed wireless communication, data are transmitted with high spectral efficiency, high data rate and reliability. But due to Rayleigh fading, the channels suffer from lot of attenuation resulting in the reduction of Energy Efficiency (EE) and Spectral Efficiency (SE). The proposed system consists of DMIMO system. It contains multiple of MIMO in a system. Here using Closed Form Approximation (CFA) method for trade-off of the EE-SE. Distributed Multiple Input Multiple Output (DMIMO) systems are form of spatial diversity in which we use multiple antennas at transmitter as well as receiver. Closed-form approximation of the Energy Efficiency vs. Spectral Efficiency (EE- SE) trade-off for the uplink/downlink of distributed multiple- input multiple-output (DMIMO) system with two cooperating base stations. This method shows tight match between closed-form approximations for EE- SE trade-off. For given a target SE requirement, there exists an optimal antenna setting that maximizes the EE. In addition, DMIMO scheme can offer significant improvement in terms of EE for both uplink and downlink configurations. While spectral efficiency increases the energy get reducing for various p*q antenna configurations.
