| Abstract(in English) | Single-carrier (SC) decode-and-forward (DF) relay using space-time block coding (STBC) overcomes propagation path loss, shadowing loss and frequency selective fading, and as a consequence, can extend the communication range while reducing the transmit power. However, in conventional STBC-DF relay, the channel state information (CSI) is required at the relay station (RS) for demodulation, decoding, and re-modulation. In this paper, we propose a STBC amplify-and-forward (AF) cooperative (STBC-Co-AF) relay which requires no knowledge of CSI at RS. In STBC-Co-AF relay, the transmitting node transmits 2-block signal to both RS and the receiving node in the first time slot and then, RS transmits amplified STBC-coded signal to the receiving node in the second time slot. The receiving node performs a series of frequency-domain equalization (FDE), diversity combining, and STBC decoding by viewing the concatenation of the channels between the transmitting node-RS link and between RS-receiving node link as an equivalent channel. We evaluate, by computer simulation, the average bit error rate (BER) performance when using STBC-Co-AF relay and show that the STBC-Co-AF relay achieves BER performance superior to Co-AF relay. |
