Performance analysis of adaptive space-time coded systems with continuous phase modulation

In modern wireless communications, it is getting urgent to make a better trade-off between reliability and effectiveness in wireless systems. In fact, the use of coded cooperation (e.g. space time coding) in multiple input and multiple output (MIMO) system has drawn much attention for this purpose. However, it needs to be further investigated how to select the space time codes (STC) adaptively. On the other hand, continuous phase modulation (CPM) is a promising technology for its merits of power and spectrum efficiency. This study is to consider adaptive space time coded CPM systems. The criterion of adaptive switching is based on the Frobenius norm and the thresholds between STC schemes. Analysis and simulation are made to the proposed system in terms of frame error rate and data rate.
