This paper presents an efficient implementation of space-time coding for broadband wireless communications. A user-friendly menu-driven Space Time (ST) trellis coding simulator with a graphical user interface (GUI) is developed. The simulator is used to predict the improved performance and diversity gains of a ST coding system through a number of parameters including type of trellis codes and channel fading. Results are presented to demonstrate the versatility of the developed simulator for predicting the performance of a ST coding system under different coding and channel conditions.
