Abstract :
Diversity-embedded space-time block coding (DE- STBC) introduced in [1] is a class of non-orthogonal STBC which can provide multiple diversity orders and transmission rates for the information symbols. This is achieved by transmitting the information symbols in layers each characterized by a diversity-rate tuple according to its QoS requirement. This paper derives a closed-form performance bound for DE-STBC over flat fading channels using outage probability analysis. Furthermore, the effective coding gain and system throughput are analyzed and optimized based on the derived outage expressions.
