Abstract

An embedded differential space-time coding method is proposed for wireless broadcast application in this work. Our previous work [1] investigated embedded space-time codes for layered media broadcast. In such a system, a transmitter sends out multi-layer source signals by encoding different layers with different space-time codes. Then, the receiver can retrieve a different amount of information depending on the number of antennas it has as well as the level of receiving power. The receiving terminals with one antenna can decode only the base layer information with a low complexity while terminals with more antennas can retrieve more layers of information. In this research, we further consider the case when the channel state information (CSI) is unknown. The differential coding technique is adopted here. Transmitted symbols are encoded as a certain combination of previous symbols so that the receiver can retrieve the information without CSI. We explore the embedded design with differential STC to enable layered media transmission. Differential detection with Kalman filtering is also investigated to help improve performance.
