Optimization of a Scalable and Adaptable Diversity/Multiplexing Trade-Off in 28 GHz Systems

摘要

This paper investigates the optimization of the feedback information required by the adaptation of MIMO techniques in a large-scale environment. The main aim is to propose three optimization techniques and compare its BER performances in a 28 GHz system. It is shown that the reduction of the feedback amount leads to a BER increase. However the "keep" approach based method can guarantee near optimal BER performances while ensuring a remarkable feedback's reduction.
