Performance Analysis of STBC Based on STTC System

Abstract

Multi-path fading is a significant problem in wireless communication systems. Therefore, we need a reliable system to overcome the multi-path fading. In this paper, we proposed the use of a STBC based on a STTC system to improve the reliability of wireless communication systems in multi-path fading environments. We also analyzed the performance of the proposed system and found it efficient. The proposed system was able to acquire not only a diversity gain and coding gain from the STTC system, but also a diversity gain from the STBC system without stimulating an additional channel bandwidth. Furthermore, the simulation results matched the theoretical Chernoff upper bound well, particularly in the high Eb/N0.
