Abstract :
Diversity embedded space-time code can be used to simultaneously transmit data streams with quality-of-service (QoS) requirements. However, the decoding complexity of existing diversity embedded codes is high since these codes are fully non-orthogonal. In this paper, group-decodable diversity embedded space-time code is proposed and constructed systematically. A code construction is presented for high Scalability in term of diversity levels and decoding complexity. Code examples are shown to achieve very low decoding complexity.
