The wireless relay systems represent an important segment in the wireless communication systems. In a simple wireless relay scenario, a source node AS needs to communicate to a destination AD, with the help of a relay AR. In this paper we introduce a new two-step relaying scheme based on superposition coding, SC-relaying. In step 1, AS broadcasts a message, created by superposition coding, to AR and AD. After decoding the information from AS, AR relays a part of this message in step 2, by… CONTINUE READING
