Abstract :
In this paper we present the effects analysis of the imperfections for practical high speed wireless multi-antenna transceiving systems. Some integration expressions are derived for evaluation when the effects of in-phase/quadrature(I/Q) imbalance is concerned. Several simulation results shown subsequently demonstrate that the existence of these imperfections brings an even bigger problem than in their traditional single antenna counterparts. All the work provides a theoretical foundation of the practical multi-antenna wireless communication systems for engineers and designers.
