Abstract
An embedded space-time coding method is proposed for wireless broadcast applications. In the proposed system, a transmitter sends out multi-layer source signals by encoding different layers with different space-time codes. Then, the receiver can retrieve different amount of information depending on the number of antennas. The receiver with only one antenna can decode only the base layer information with a low complexity, while the receiver with more antennas can retrieve more layers of information. We derive an analytic bound on the error probability, and show both analytic and experimental results in this work.
