Abstract

Abstract:

Massive multiple-input multiple-output（MIMO）refers to the idea equipping cellular base stations with a very large number of antennas，and is a communication way of severing several users. Widely-linear optimized block diagonalization type precoding techniques was proposed to alleviate the impact of IQ imbalance in the downlink massive multi-input multi-output systems. Numerical results show that significant performance can be gain compared to BD and WL-BD.

Key words: massive MIMO, IQ imbalance, precoding algorithm, error rate, block diagonalization precoding algorithm
