Performance Analysis of CPM in Multi-Cell Massive MIMO System

Abstract

Continuous phase modulation (CPM) has many desirable features such as power efficiency and spectrum efficiency. This paper considers continuous phase modulation in massive MIMO system. Especially in cellular wireless system, we can obtain more accurate channel state information in uplink time division duplexing (TDD) transmission via employing different CPM modulation index h. On the basis of that scheme, the method of linear precoding can achieve better performance in the reverse link. Finally, simulated results have verified the proposed system.
