This paper evaluates the performance of space-time coding techniques applied to a digital audio broadcasting (DAB) system. The proposed scheme uses two transmitter antennas and one receiver antenna. This work investigates the way space and time diversity can decrease the distortion due to multipath fading and interference from other users and improve bit error rate. Numeric results show that space-time codes are a good way to improve the performance of a system DAB and the quality of additional information services.
