Analysis on the impact of phase offset on massive antenna array

Massive antenna array has been recognized as an important technology for the next generation mobile system. Although there are many researches on the theory of massive antenna array system, there are limited studies on the realization aspects about the massive antenna system. This paper investigates the non-ideal factors in the massive antenna system, especially the phase offset. Our analysis and simulation results demonstrate that massive antenna array system have a better performance than the small-scale antenna array system to the phase shift.
