TRANSMISSION SCHEMES FOR RELAY |
摘要 |
<p>Techniques for processing and forwarding transmissions by a relay are disclosed. In one aspect, an orthogonal distributed space-time frequency code (DSTFC) scheme that supports full-duplex relay operation and mitigates self-interference is disclosed. With the orthogonal DSTFC scheme, a source node transmits a same modulation symbol on two subcarriers in one symbol period. The relay obtains two received symbols from the two subcarriers and generates two output symbols based on these received symbols such that the output symbols and the modulation symbol are orthogonal at the relay and a destination node. In another aspect, a distributed Alamouti scheme is disclosed in which the source node transmits two modulation symbols on two subcarriers in each of two consecutive symbol periods. The relay obtains two received symbols from the two subcarriers in one symbol period and generates two output symbols based on the received symbols and in accordance with an Alamouti code.</p> |
