SOURCE ANTENNA SWITCHING SCHEME FOR NON-ORTHOGONAL DECODE-AND-FORWARD PROTOCOL

摘要

PURPOSE: A source antenna switching scheme for non-orthogonal decode transmitting protocol is provided to obtain big diversity by source antenna switching in non-orthogonal decode transmitting protocol. CONSTITUTION: A signal of source node is transmitted in the relaying node and destination node(S1). The space time code is composed(S1-1). The space time code is transmitted(S1-2). The source node and relaying node constitute the dispersion space time code. The dispersion space time code is transmitted to the destination node(S2). The relaying node decodes the received signal as described above(S2-1). In signal and relaying node of the source node, the decoded signal as described above is composed as the dispersion space time code(S2-2).
