Abstract :
Utilization of distributed antennas provides an additional dimension for performance enhancement in 4G and beyond cellular networks. Intelligent remote antenna allocation and practical transmission scheme are two most important aspects for the design of DAS. In this study, a sectorized distributed antenna structure is introduced and correspondingly, power adjusted beam switching as a practical transmission scheme is proposed with periodic beam switching and dynamic power allocation. Simulation results show that the proposed DAS structure and transmission scheme improve the capacity in all SINR regions especially with optimal power allocation.
