Abstract: 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).

Abstract: PURPOSE: A blind SLM(Selected Mapping) method is provided to reduce encoding complexity and minimize the performance degradation of a BER(Bit Error Rate). CONSTITUTION: A transmission end selects a symbol sequence which has the smallest PAPR among OFDM carrier wave symbol sequences. The transmission end partitions the OFDM carrier wave symbol sequences into a constant period. A sectional phase is rotated according to the m-sequence which is used every OFDM carrier wave symbol sequence.
