Abstract (in Japanese) (See Japanese page) 
(in English) Recently, we proposed space-time block coded (STBC) amplify-and-forward (AF) relay for wireless relay communication using unmanned aircrafts (UAs). In STBC-AF relay, UAs perform AF-STBC encoding consisting of conjugate operation and block exchange only. Then, the destination node performs frequency-domain equalization (FDE), diversity combining and linear STBC decoding by using an equivalent channel which is a concatenation of the channels of the source-UA link and the UA-destination link. Our previous study showed that STBC-AF relay can improve bit error rate (BER) performance by increasing the number of UAs. However, when the number of UAs is more than 3, the code rate of AF-STBC decreases, resulting in the throughput degradation. In this paper, we proposed STBC-AF relay with cyclic delay diversity (CDD). In STBC-CDD-AF relay, a number of UAs are divided into 2 groups, and then AF-STBC encoding for 2 UAs is performed by the group. And then, the each UA in each group adds different cyclic delay to each transmit signal. We evaluate, by the computer simulation, the average BER performance and throughput performance when using STBC-CDD-AF relay and showed that STBC-CDD-AF relay achieves higher throughput than STBC-AF relay when the number of UAs is 4.
