This paper proposes a combination of space-time block codes (STBC) and superposition modulation (SM). It is aimed to obtain both high reliability and throughput. Conventional STBC can not achieve high throughput by passing the relay. The proposed scheme improves the throughput by using SM. Additionally, it can transmit signals of source and relay at the same time.
